Question

A car starting from rest accelerated at the rate of 0.5 m/s². What would be the final velociety of the car and how much time would it take to cover 1.6kms?

Answer 1

1) 800m/s

2) 2 seconds

Step-by-step explanation:

Acceleration= velocity/time

Where acceleration= 0.5 m/s²

Time= 1.6kms= 1.6×10^3 seconds

If we substitute we have

0.5=v/(1.6×10^3)

V=800m/s

the final velociety of the car is 800m/s

Velocity= distance/time

800= (1.6×10^3)/ time

Time= 1.6×10^3/800

=2 seconds

Hence the time it will take to cover is 2seconds
