Question

Describe the motion of a body which is accelerating at a constant rate of 10 m s^–2. If the body starts from rest, how much distance will it cover in 2 s ?

Answer 1

We have to find the distance travelled by the body. We have the following information given,
So, Initial velocity, (u) = 0 m/s
Acceleration, (a) = 10 m/s²
Time taken, (t) = 2 s
We can calculate the distance travelled by using the 2^nd equation of motion,
`s = ut + 1/2 at^2`
Put the values in above equation to find the distance travelled by the body,
`(s) = 0(2) + 1/2(10)(2)^2`
= 20 m
