Question

A car starting from rest is uniform accelerated,so that its velocity is 6sec in 58m/h a brake is the applied to it to bring it stop in 5sec find it's acceleration and it's retardation

Answer 1

a = ∆v/∆t

acceleration is (58m/h)/(6s)
retardation is (-58m/h)/(5s)

Answer 2

Please proofread this.
