Question

.A racing car accelerates uniformly from 20 m/s to 40 m/s in 3 seconds. Determine the acceleration of the car and the distance travelled.

Answer 1

Answer:

a=20/3m/s2, s=90m

Explanation:

u=20m/s

v=40m/s

t=3s

v=u+at

by sub the values a=20/3 m/s^2

v^2-u^2=2as

by using above eq s=90m
