Question

A race car accelerates at a constant rate from 20 m/s to 60 m/s in a time of 2 seconds. What is the car’s acceleration?

Answer 1

`\huge\fbox{Answer ☘}`

Given ,

initial velocity , u = 20 m/s

final velocity , v = 60 m/s

time taken = 2 seconds

Now ,

`\bold{acceleration = (v - u)/(t) } \\ \\ = > \bold{ (60 - 20)/(2) } \\ \\ = > \bold{(40)/(2) } \\ \\ \bold{ => 20 \: ms {}^( - 2)}`

hope helpful~
