Question

starting from rest, a car accelerates to 45 m/s in 1 minute. what is the average acceleration of the car in m/s^2 ?

Answer 1

given us,

initial velocity (u)= 45m/s

time(t)= 1 min

final velocity (v)=?

here,

average acceleration = v-u/t

= v- 45/1

v= 45/1

:. v=45m/s

:. the average acceleration of the car in m/s^2 is 45m/s

Step-by-step explanation:

we can use acceleration formula
