Answer to Question #141834 in Physics for I. Ama

Question

You will use this information to answer all questions on this quiz: An otherwise flat road runs over a hill that rises m above the flat part. The top of the hill follows the curvature of a 20-meter radius circular arcA 1,600 kg car starts from rest at a stop sign 50 meters before the beginning of the hill, then accelerates uniformly it reaches the beginning of the hillOnce the car reaches the beginning of the hill coasts with the engine not supplying any additional forward-forceYou may ignore the effects of friction and air resistance


A) Calculate the magnitude of the acceleration of the car (ln m/s^ 2 ) over the first 50 meters

B) How long (in seconds) does it take the car to move from the stop sign to the beginning of the hill?

Calculate the magnitude of the net force (in Newtons) required to accelerate the car over the first 50 meters Round your answer to the nearest whole number Enter only a number in the blank.

C)



D)
