1-lb block and a 100-lb block are placed side by side at the top of a frictionless hill. Each is given a very light tap to begin their race to the bottom of the hill. In the absence of air resistance, what can you conclude about the outcome of the race?

Respuesta :

Answer:

finish at the same time

Explanation:

Force equals mass times acceleration. Without friction the net force on both will be equal to component of the force of gravity. Therefore the net force will be mass time acceleration due to gravity times the incline of the hill. Since net force equals mass times acceleration. Now we set net force equals mass times acceleration and the mass will cancel out giving both block the same acceleration and therefore they will finish at the same time

Complete Question

The complete question is shown on the first uploaded image

Answer:

The answer is C

Explanation:

The reason for the solution above is that since both the blocks are on the same incline , both experience the same acceleration and hence travel the length of incline in the same interval of time.
