A toy is thrown vertically upward with a speed of 12m/s from the edge of a cliff 75m high. How much later does it reach the bottom of the cliff? Whats its speed just before hitting the ground? What total distance did it travel?
15. A man is running to cateh a bus at his top speed of 6 m/s. The man is 25 m behind the b starts to move forward with an acceleration of 1 m/s e man catch the bus? If yes, then fiud out when and where it happens. If no, then determine how w an accurate position-versus-time graph of this scenario for both the man and the bus on the same (c) Repeat Parts (a) and (b) assuming that...
A man is running at speed c (much less than the speed of light) to catch a bus already at a stop. At t = 0, when he is a distance b from the door of the bus, the bus starts moving with the positive acceleration a. Use a coordinate system with x = 0 at the door of the stopped bus. Draw a position vs. time graph for both the man and bus on the same graph. Make sure...
a ball player catches a ball 3.12 s after throwing it vertically upward. With what speed did he throw it? What height did it reach?
At the local playground, a child on a swing has a speed of 2.12 m/s when the swing is at its lowest point. Part A: To what maximum vertical height does the child rise, assuming he sits still and "coasts"? Ignore air resistance. Part B: How do your results change if the initial speed of the child is halved?
You throw a ball straight upward with an initial speed of 12 m/s. What is the objects acceleration on the way up and on the way down? Calculate the maximum height the ball can reach. What is the total flight time of the ball?
A 31.0 kg child on a swing is displaced by a maximum angle of 20 degrees to the vertical above her rest position. Assuming no loss of energy and that the swing's rope is 2m long: a) At what point during the swing will she attain her maximum speed? b) What will be her maximum speed through the subsequent swing? c)Assuming this maximum height was the result of one push from her parent, what was the average force exerted by...
11 A stone is thrown vertically upward with an initial speed of 20 m/s. the time it takes to reach the maximum height is equal to: (2 Points) 1 1.5 3 4 2 12 On an v-t graph the slope at any time equals the: (2 Points) onood
A model rocket is launched straight upward with an initial speed of 54.7 m/s. It accelerates with a constant upward acceleration of 1.94 m/s2 until its engines stop at an altitude of 131 m. What is the maximum height reached by the rocket? How long after lift off does the rocket reach its maximum height? How long is the rocket in the air?
