Question

A bus start from rest. If the acceleration is 2 m/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=0x2+1/2×2×2^2

S=0+ 1/2 ×2×4

S=1/2x8

Distance travelled, S=4m

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

V=0+2x2

Final velocity, V=4m/s.
