Question

a body starts from rest after 8 seconds its velocity becomes 20 metre per second find acceleration and distance​

Answer 1

Explanation:

Intial Velocity = o m/s

Final velocity = 20 m/s

Time = 8 seconds

Acceleration = Final velocity - Initial Velocity

------------------------------------------

Time

Acceleration = 20-0

--------

8

Acceleration = 2.5

By second equation of motion

s= ut + 1/2at²

s = 0×8 + 1/2 × 2.5×8²

s = 0+ 1/2 × 2.5 ×64

s = 0+80

s = 80m
