- A celebrated Mark Twain story has motivated contestants in the Calaveras County Jumping Frog Jubilee, where frog jumps as long as 2.2 m have been recorded. If a frog jumps 2.2 m and the launch angle is 45, find (a) the frogs launch speed and (b) the time the frog spends in the air. Ignore air resistance.A rock is tossed from the top of a building at an angle of 20° above the horizontal with an initial speed of 17 m/s. The rock lands on the ground 2.9 s after it is tossed. What is the height of the building (in m)? mA soccer ball is kicked from the ground with an initial speed of 19.0 m/s at an upward angle of 44.2".A player 51.8 m away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground? Neglect air resistance.Use g=9.81 m/s². Number i Unit
- The basketball bounces straight back up off the ground and reaches a maximum height of 4.00m. a)With what speed did the ball leave the ground? (It is perfectly natural for this to be less than the speed it had before it hit the ground.) The basketball hoop is 3.05 m above the ground. The ball will pass the position of the hoop twice –once on the way up and a second time on the way down. b)Determine the ball's velocity (magnitude and direction) as it reaches the height of the hoop on its way down.A soccer ball is kicked from the ground with an initial speed of 19.9 m/s at an upward angle of 41.3".A player 50.8 m away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground? Neglect air resistance.Use g=9.81 m/s?. Number i UnitA soccer ball is kicked from the ground with an initial speed of 19.1 m/s at an upward angle of 43.4". A player 53.4 m away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground? Neglect air resistance. Use g=9.81 m/s². Number i Unit
- 8. A ball is thrown vertically upward from the edge of a bridge 29.5 m high with an initial speed of 13.0 m/s. The ball falls all the way down and strikes the water below. Determine the magnitude of the velocity of the ball just before it strike the water. m/s O ssf60 s ssf60 f60A hot air balloon is travelling vertically upward at a constant speed of 3.7 m/s. When it is 27 m above ground, a package is released from the ballon. a) After it's released, for how long is the package in the air in units of s? Acceleration of gravity is 9.8 m/s/s. b)What is the speed just before impact with the ground in m/s? c) Now assume the hot air balloon is traveling vertically downward at a constant speed of 3.7 m/s. After the package is released, how long is it in the air in s? d) What is the speed just before impact with the ground in m/s?If you drop an object from a height of 1.3 m, it will hit the ground in 0.52 s. If you throw a baseball horizontally with an initial speed of 42 m/s from the same height, how long will it take the ball to hit the ground?s
- A student releases a marble from the top of a 160cm ramp. The marble increases speed steadily and reaches the bottom of the ramp in 2.70s. a)What was the magnitude of the marble's acceleration? b)What was the marble's final speed?Determine s and a when t= 3 s if s=0 when t= 0. v (m/s) t (s) 4 2. 2.More people end up in U.S. emergency rooms because of fall-related injuries than from any other cause. At what speed v would someone hit the ground who accidentally steps off the top rung of a 8.00 ft tall stepladder? (That step is usually embossed with the phrase "Warning! Do not stand on this step.") Ignore the effects of air resistance. Let the +y direction point vertically upward and the origin be on the ground.
