A child on a bridge throws a rock straight down to the water below. The point where the child released the rock is 99 m above the water and it took 1.9 s for the rock to reach the water. Determine the rock's velocity (magnitude & direction) at the moment the child released it. Also determine the rock's velocity (magnitude & direction) at the moment it reached the water. Ignore air drag.

In the blizzard of ’88, a rancher was forced to drop hay bales from an airplane to feed her cattle. The plane flew horizontally at 160 km/hr and dropped the bales from a height of 80 m above the flat range, (a) She wanted the bales of hay to land 30 m behind the cattle so as to not hit them. Where should she push the bales out of the airplane? (b) To not hit the cattle, what is the largest time error she could make while pushing the bales out of the airplane? Ignore air resistance.
A basketball center holds a basketball straight out, 2.0 m above the floor, andreleases it. It bounces off the floor and rises to a height of 1.5 m.a) What is the ball’s velocity just before it hits the floor?b) What is the ball’s velocity just after it leaves the floor?c) If the ball is in contact with the floor for 0.02 seconds, what are the magnitudeand direction of the ball’s average acceleration while in contact with the floor?
1) At the Blue Jays game, R. A. Dickie (height = 1.2m) throws a baseball straight in the air %3D (140g) with 95N of force for 30cm. a. What is the speed of the ball 2.4 m above the ground? b. What is the maximum height of the ball (assuming no air resistance)?
An eagle carries a fish with its talon flying 15 m/s at an angle 25 degrees. At some point, this fish is able to wiggle free form the eagle and is released, resulting in the fish falling to the ground. If it takes the fish 3 seconds to reach the ground: How high was the fish when released? What was the magnitude of the fishe's velocity when it reached it's highest point after wiggling free?
A boy drops a stone with no initial velocity from the top of a building and it hits the ground in a time of 2.19 s later. What is the height of the cliff, in units of meters? You may assume that air resistance is negligible. Give the answer as a positive number. Question 3 A projectile is fired with initlal velocity vo - 6.00 m/s and its direction is 8 30.0° with the horizontal. What is the max height of the projectile in unit of meters?
A ball is thrown with an initial velocity of 100m/s at an angle of 40o above the horizontal. a. How far from the throwing point will the ball attain its original level? b. Calculate the height of the highest point that the ball reaches during its travel.
A man stands on the roof of a 18.0m tall building and throws a rock with a velocity of magnitude 24.0 m/a at an angle 37 degrees above the horizontal. You can ignore air resistance. Assume thag the rock is thrown from a level off the roof. a.) Caculate the maximum height above the roof reaches by the rock b.) calculate the magnitude of the velocity of the rock just before it strikes the ground. c.) calculate the horizontal distance from the base of the building to the point where the rock strikes the ground
Professional golfers can drive the ball over 200 m. While air resistance is significant, its effects are nearly canceled because lift is gained from backspin on the ball, and so a reasonable description of the ball’s trajectory is obtained if air resistance is neglected. Suppose a golfer hits a ball 200 m on level ground, giving it an initial velocity at an angle of 45o. The duration of the impact of the club and ball has been measured to be 1.00 ms. a) Calculate the velocity of the ball just after it is struck b) What is the 0.0450 kg ball's change in momentum?
A golf ball is driven off a tree that is elevated 10m above fairway. The initial velocity of the ball is 40m/s with an angle of 40° at the horizontal. a. Maximum height? b. Range? c. Velocity of ball when it reaches fairway?
A river is about 5.7 m wide. Suppose an athlete wants to jump “over the river” and leaps at an angle of 35o with respect to the horizontal. What is the minimal initial speed that would allow the athlete to clear the gap? How much time is the athlete in the air? (please include images to help me understand :))
A Tennis player hits a ball 2.0 m above the ground at an angle 5º above the horizontal. The horizontal distance to the net is 7.0 m and the net is 1.0m high. What is the minimum initial speed, vi, needed to clear the net? (Hint: this is like the problem done in the handout, but since we don’t know the initial speed, we have to find horizontal and vertical components and the time symbolically and carry that through.) Im so confused and don't know where to start...
