Question

It takes a car 2 minute(s) to go from rest to 25 m/s east. What is the acceleration

Answer 1

Explanation:

we first convert 2 minutes to seconds,which will give us 120s (2×60).

v=u +at where (v=final velocity,u is the initial velocity,a is the acceleration of the car and t the time taken)

V=25 m/s

u=0 m/s since the car started from rest

t=120s

substituting the values we get

25=0+a (120)

25=120a (diving both sides by 120 we get)

a=0.208m/s^2
