Question

An object starts from rest covers a distance of 200m with an acceleration of 1 m/s. Calculate the Kinetic Energy attained.

Answer 1

Explanation:

Initial velocity u=0 acceleration a=1ms

−2

Time interval t = 4 seconds

Distance travelled =s=ut+ 21 at 2

s=0×4+21 ×1×42

=0+ 21×1×16

=8m.
