Question

A car started from rest and increased its speed to 60 m/s in a minute. The acceleration of the car is ___ m/s2.

hintHint:

Acceleration is the rate of change in velocity.

The correct answer is: 1


    Given:
    Initial velocity = 0
    Final velocity = 60m/s
    Time = 60sec
    To find:
    Acceleration = ?
    Solution:
    v space equals space u space plus space a t
60 space equals space 0 space plus space a space cross times space 60 space
a space equals space 1 m s to the power of negative 2 end exponent

    An object starts from rest. It means that _____.

    Rest implies that the body was stationary with respect to the ground. Any body which doesn't move has zero velocity, since it doesn't covers any distance. Thus, any body starting from rest has initial velocity= zero.
