Question

A car starts from rest and has accelaration of 2ms-2 .find the speed of the car after 1 minute

Answer 1

Answer:

120 m/s

Explanation:

a=2m/s2

t=1 minute=60 seconds

i(initial velocity)=0(since the car starts from rest)

v=to find

Since acceleration is the rate of change of velocity

Therefore,

a=(v-u)/t

2=(v-0)/60

v=60*2

v=120 m/s
