Question

if a body starts from rest and attains a velocity of 20 metre per second in 8 seconds find the acceleration produced in the body​

Answer 1

2.5 m/s^2

Step-by-step explanation:

the equation to find acceleration is
`(v - v_(0) )/(t)` where
`v_(0)` is the initial velocity, v is the current velocity, and t is the total time

so plug in your values:
`(20 - 0)/(8)`

that turns into 20 ÷ 8

this equals 2.5 m/s^2
