- The Zero Gravity Research Facility at the NASA Glenn Research Center includes a 145 m drop tower.This is an evacuated vertical tower through which, among other possibilities, a 1-m-diameter sphere containing an experimental package can be dropped. (a) How long is the sphere in free fall? (b) What is its speed just as it reaches a catching device at the bottom of the tower? (c) When caught, the sphere experiences an average deceleration of 25g as its speed is reduced to zero.Through what distance does it travel during the deceleration?A cannon fires a shell traveling 150 m/s in the horizontal direction and 150 m/s in the vertical direction. The cannon is on a cliff 100 meters above the ocean water below. What is the maximum altitude (in meters) above the water the cannon ball reaches?An object is hovering about the surface of the earth. It begins to experience a gravitational acceleration of 2.0 m/s2. How high is it above the surface of the earth?
- Gravitational acceleration is 5.13 m/s2. Object is thrown upward with a velocity of 13.3 m/s. What is the maximum height reached by the object?A Deadly Virus. On your flight out of South America your cargo plane emergency-lands on a deserted island somewhere in the South Pacific. Because it was a beach landing, the pilot skids the plane on its belly rather than lowering the landing gear. The landing is rough: an initial vertical drop followed by an abrupt horizontal deceleration. When the dust settles, the pilot and your scientist colleagues are all okay, but you know there might be a big problem. Your team is transporting samples of a deadly virus from a recent breakout in a small village. The samples were packed in a cryogenically cooled container that has a special seal that may leak if it exceeds an acceleration greater than 10g. The container has a mechanical accelerometer gauge that measures the maximum vertical deceleration in case the container is dropped. It reads a value of a -7.00g. However, you are still worried: there was another component of the acceleration. You get out of the plane and measure the length of…lo, a satellite of Jupiter, is the most volcanically active moon or planet in the solar system. It has volcanoes that send plumes of matter over 500 km high. Due to the satellite's small mass, the acceleration due to gravity on lo is only 1.81 m/s², and lo has no appreciable atmosphere. Assume that there is no variation in gravity over the distance traveled ▼ What must be the speed of material just as it leaves the volcano altitude of 310 km?

- Julie, mass 36kg, has invented a new ride called the Human Launcher. It is basically a platform that springs people straight up into the air. She is testing it, standing on a bathroom scale on the platform. As the platform springs 10.0m upward from rest, Julie notices the scale reads 600.0N. Once it reaches ground level, the platform suddenly stops, but Julie doesn't, and is launched up into the air. What is the maximum height above the ground that Julie will reach? (the ride was deemed unsafe and cancelled) *= nut 10.0m groundThe earliest drop towers were used for the purpose of making lead shots for muskets. The procedure involved releasing droplets of molten lead from the top of the tower. As the droplets of lead fell through the tower, they formed a spherical droplet. If given enough free fall time, the droplet of molten lead would solidify to form the perfect spherical shot. The tallest of these drop towers in the United States was a 230-foot tower built in Baltimore. Suppose that lead free falls through a drop tower for a distance of 63.9 meters a) Determine how much time (in seconds) it takes the lead shot to fall this distance of 63.9 meters. b) Determine how fast (in m/s) the lead shot is moving after free falling for 63.9 meters, right before hitting the groundThe ceiling of an arena is 77 m above the floor. What is the minimum speed that a thrown ball would need to just reach the ceiling? (in m/s)
- A small rocket is launched straight up. When at a height of 5.0km and velocity of 200.0m/s, it releases its booster and enters free fall.

Each vertical loop, instead of being circular, is shaped like a teardrop. The cars ride on the inside of the loop at the top, and the speeds are fast enough to ensure that the cars remain on track. The biggest loop is 40.0m high. Suppose the speed at the top is 14.4m/s and the corresponding centripetal acceleration is 2g. (a) What is the radius of the arc of the teardrop at the top? (b)If the total mass of a car plus the riders is M, what force does the rail exert on the car at the top? (c) Suppose the roller coaster had a circular loop of radius 21.4 m. If the cars have the same speed, 14.4 m.s at the top, what is the centipetal acceleration at the top?A prankster flips a coin off of the Empire Building at a height of 1054 feet above the ground. The initial vertical velocity of the coin is 1.20m/s. In real life, air resistance would limit the maximum speed the coin can attain during its fall, but if air resistance were not a factor and assuming it has practically no horizontal motion, answer the following questions. (1 foot = 0.3048m) a. What would the coin's velocity be when it hits the ground? b. How long would it take to hit? c. How high would the coin be halfway through the total falling time, and how fast would it be falling then?
