A 500kg car which was initially at rest travelled with an acceleration of 5m/s², its kinetic energy after 4 seconds was A. 10⁵J B. 2.5 x 10³J, C. 2 x 10³J D. 5 x 10³J E. 5 x 10⁵J
ANSWER: Option A
KE = ½mv²
Since v = u + at
KE = ½m(u + at)²
Substitute the values in the equation above to find your answer.
Remember u = 0 as the car started from rest.
