physics

Two objects moving with constant acceleration starting from rest are to cover the same distance. If the second is to cover that distance in ¼ of the time would need

a: a quarter of the first’s acceleration.

b: a half of the first’s acceleration.

c: sixteen times the first’s acceleration.

d: eight times the first’s acceleration.

  1. distance=1/2 a t^2
    a= 2 distance/t^2

    so if the new t is 1/4, the new a must be 16 times
