Question

A car is moving initially at 30 m/s comes gradually at stop at 900 m . What is acceleration of the car ?

Answer 1

The acceleration of the car is 0.5 meters per seconds square.

Given the following data:

• Initial velocity, U = 30 m/s

• Distance, S = 900 meters

Note: The final velocity (V) of the car would be zero (0) m/s when it comes to a stop.

To find the acceleration of the car, we would use the third equation of motion;

Mathematically, the third equation of motion is given by the formula;

$V^2 = U^2 - 2aS\\\\0 = 30^2 - 2a(900)\\\\0 = 900 - 1800a\\\\1800a = 900\\\\a = \frac{900}{1800}$

Acceleration, a = 0.5 $m/s^2$

Therefore, the acceleration of the car is 0.5 meters per seconds square.
