Explanation:

Given

a =2m/s²

As car moves from rest (t=0) so u=0m/s

What is displacement and velocity of car at t=2sec?

Displacement=ut+1/2at²=0×2+1/2×2×(2)²

=0+4

= 4m

Velocity=displacement/time=4/2=2m/s

At what time car is moving with 10m/sand also find displacement of car?

u=0m/s v=10m/s a =2m/s²

v²-u²=2as

10²-0²=2.2.s

100=4.s

s=100/4

s=25m

velocity=displacement/time. 10m/s =25/time

time =25/10

time=2.5sec
