Question

a body starts from rest and moves with a uniform acceleration of 2 metre per second square what will be the velocity and the displacement at the end of 10 second​

Answer 1

u=0

a=2

v=0+2*10

v=20m/s

v2-u2=2aS

400-0=2*2*S

S=100m

Answer 2

u=0m/s

a=2m/s^2

t=10s

By using, v=u+at

v=0+2×10

v=20m/s

Now ,by using 2as=v^2-u^2

2×2×s=(20)^2-0

4s=400

s=100 m

Therefore, Displacement =100 m

velocity=20m/s
