Question

A bus starts from rest.If the acceleration is 2m/s^2.Find i)the distance travelled ii)the velocity after 2 seconds

Answer 1

Answer:

u=0m/s

a=2m/s^2

t=2sec

Explanation:

1) We know that ,S=ut+1/2at^2

S=0×2+1/2×2×2^2

S=0 + 1/2 ×2×4

S=1/2×8 Distance travelled, S=4m

2)As we know that, V=u+at

V=0+2×2

Final velocity, V=4m/s.

Answer 2

Answer:

u=0m/s

a=2m/s^2

t=2sec

Explanation

1) We know that ,S=ut+1/2at^2

S=0×2+1/2×2×2^2

S=0 + 1/2 ×2×4

S=1/2×8 Distance travelled, S=4m

2)As we know that, V=u+at

V=0+2×2

Final velocity, V=4m/s.
