Question

A race car accelerates uniformly from 12 m/s to 52 m/s in 2 seconds. Determine the acceleration of the car.

Answer 1

The acceleration of the car is
`20 m/s^(2)`

Solution:

According to the question:

Initial velocity of the car, u = 12 m/s

Final velocity of the car, v = 52 m/s

Time interval for the change in velocity,
`\DeltaT = 2 s`

The rate at which the velocity of an object varies is referred to as its acceleration:

`a = (v - u)/(\Delta T)`

`a = (52 - 12)/(2) = 20 m/s^(2)`
