Amagic medallion is suspended from a string inside a compartment of hogwarts express which is running straight westwards on horizontal tracks. a) draw a free-free body diagram for the medallion if the train is moving at constant speed. b) draw a free-body diagram for the medallion if the train is accelerating at a constant rate. indicate acceleration and the direction of the net force. c) calculate the angle the string makes with the vertical if the train accelerates at a constant rate from rest to 20 m/s in 10 seconds. d) if the mass of the medallion is doubled, how will the angle change?

The cheetah is considered the fastest running animal in the world. cheetahs can accelerate to a speed of 20.1 m/s in 2.50 s and can continue to accelerate to reach a top speed of 28.1 m/s. assume the acceleration is constant until the top speed is reached and is zero thereafter.1) starting from a crouched position, how long does it take a cheetah to reach its top speed? (express your answer to three significant figures.) s2) how far does it travel in that time? (express your answer to three significant figures.) m3) if a cheetah sees a rabbit 120 m away, how long will it take to reach the rabbit, assuming the rabbit does not move? (express your answer to three significant figures.)
