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 with a horizontal velocity along level ground. While running, he encounters a 2.21 m vine of negligible mass; the vine was hanging vertically from a tall tree limb and the end of the vine is directly level with his center mass. The man decides to grab the vine and swing, because he loves experiencing uniform circular motion. At the maximum height, he takes a mental note that the angle the vine makes with the vertical is...
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?
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...
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 father fashions a swing for his children out of a long rope that he fastens to the limb of a tall tree. As one of the children swings from this rope that is 6.40 m long, his tangential speed at the bottom of the swing is 7.45 m/s. What is the centripetal acceleration, in m/s2, of the child at the bottom of the swing?
