Question

Quizplus · Accepted Answer

Acceleration (a) = (final velocity (v) - initial velocity(u))/time(t)
Here, initial velocity (u) = 0 m/s
final velocity (v) = 15 m/s
time (t) = 10 s
Therefore, a = (15-0)/10 = 1.5 m/s^2
Hence, the correct answer is B.

A Car Starts from Rest and Reaches a Speed of 15
