Question

A car starts from rest and accelerates uniformly at 2 m\s2 for 10 sec. find the velocity andf displacement at the end of 10 seconds

Answer 1

a= 2m/s^2
Vi= 0m/s
T= 10s

Working out the velocity

Vf= Vi + at
Vf= 0m/s + (2m/s^2)(10s)
Vf= 20m/s

Working out the displacement

Sx= 1/2at^2
=1/2 (2m/s^2)(10s^2)
Sx= 100m

The Final velocity is 20m/s and the total displacement is 100m
