Question

A car starting from rest accelerates uniformly along a straight line.If it attains a velocity of 120kmph in 12s , what is the acceleration of the car in m/s2?​

Answer 1

Answer:

Explanation:

U (Initial Velocity) = 0m/s

V (Final Velocity) = 120 km/h = 120*5/18 = 33.33 m/s

T (Time) = 12s

A (Acceleration) = V-U/T

                           = 33.33-0/12

                           = 33.33/12

                           = 2.7774
