Question

A body starts from rest and moves with a uniform accleration of 10 m/s2 what is the distance travelled in 2nd second

Answer 1

Answer:

The distance travelled by the body in 2 seconds will be 20 metres.

Explanation:

Given that:

Initial Velocity (u)=0 m/s

Time (t)=2 seconds

Acceleration (a)=10m/s^2

To find:

Displacement (s)=?

Formula:

s=ut+1/2×at^2

Calculation:

From formula,

s=0×2+1/2×(10)(2)^2

s=1/2×(10)(2)^2

s=1/2×(10)(4)

s=1/2×40

s=20m
