Question

A cyclist started from rest and attained a velocity of 4 m/s in just 4 secs. What is the acceleration of the body?

Answer 1

change in velocity:- 4 m/s
Time :- 4 sec
acceleration:-?
acceleration=change in velocity
time
a= 4m/s
4 sec
a= 1 m/s^2

Answer 2

Acceleration can be found by the formula below.
$a = \frac{v-u}{t} \\ a= \frac{4-0}{4} \\ a=1 m/s^{2}$
