Question

A car travelling in a straight line has a velocity of 5.0 ms–1 at some instant. After 4.0 s, its velocity is 8.0 ms–1. What is its average acceleration in this time interval?

Answer 1

Answer:

axasaa

Explanation:

Answer 2

Explanation:

u=5.0m/s

t=4.0a

v=8.0m/s

Average acceleration = a= u (v-u)/t

= a = (8.0-5.0)/4.0

= a = 3.0/4.0

= a = 0.75 ms square
