Question

Your car is initially at rest when your hit that gas and the car begins to accelerate at a rate of 2.857 m/s/s. The acceleration lasts for 15.5 s. What is the final speed of the car and how much ground does it cover during this acceleration?

Answer 1

Given parameters:

Initial velocity = 0m/s

Acceleration = 2.857m/s²

Time = 15.5s

Unknown:

Final speed of the car = ?

Solution:

We use one of the motion equations to solve this problem;

V = U + at

Where V is the final velocity

U is the initial velocity

a is the acceleration

t is the time taken

V = 0 + 2.857 x 15.5 = 44.28m/s
