Question

Starting from rest and object accelerates at the rate of 12 metre per second square what is the velocity of the object at the end of 3 seconds

Answer 1

Given,
Initial velocity=0
Final velocity =12m/se2
Displacement =Final-initial
=12-0
Displacement =12
Velocity=Displacement/Time
V=D/T
V=12/3
V=4m/s

Answer 2

Explanation:

Explanation:

u=0

a=12m/s²

t=3s

v=u+at

=>v= 0+12*3

=>v=36m
