Question

A drag racer starts from rest and acclerates to a velocity of 30 m/s in 1 s. What is the acceleration of the racer?​

Answer 1

Step-by-step explanation:

a=v-u/t

v=final velocity

u=initial velocity

u=0(when a body starts from rest the initial velocity is 0)

v=30m/s

a=30-0/1

=30m/s²
