Question

a vehicle accelerates uniformly from a velocity of 8km/ hr to 24 km/hr in 4 secs. determine the acceleration and the distance travelled by it during that time​

Answer 1

Answer:

initial velocity = 8 km/hr final velocity = 24 km/hr, time =4 sec

weknow acceleration=change in velocity/time

therefore a=24-8/4

=16/4

=16/0.00111111 hr

=14400.0144hr

Explanation:

Answer 2

Explanation:

24*18/5= 86.4m/s( final velocity)

8*18/5=28.8m/s( initial velocity)

a=v-u/t =

86.4-28.8/4s =14.4 m/s^2
