Question

what is the acceleration of a car whose velocity changes from rest position to 30 km in 2 seconds​

Answer 1

Answer:

Initial velocity (u)=0 (object starts from rest

Final velocity (v)=30km/h

Velocity=36km/h

Velocity=36×5/18

V=10m/s

Time(t)=2 seconds.

Acceleration (a)=??

a=v-u/t

a=10-0/2

a=10/2

a=5

Therefore a = 5m/s²
