Question

a car starts from rest and increases its velocity at constant rate until it reaches a speed of 20 m/s in 5 seconds what is the acceleration of the car

Answer 1

4m/s²

Step-by-step explanation:

initial velocity(u)=0m/s

final velocity (v)=20m/s

time taken(t)=5 sec

Acceleration of car(a)=(v-u)/t

=(20-0)/5

= 20/5

=4m/s²
