Acar’s speedometer reads 20 m/s after accelerating, from a standing start, for 25s. what was the magnitude of its acceleration?

A car’s speedometer reads 20 m/s after accelerating, from a standing start, for 25s. The magnitude of the car's acceleration is 0.8 m/s².

Acceleration can be defined as the change in the velocity of an object over an extended period of time. An object's acceleration is brought by a given amount of force which can either be through a push or a pull.

Given that:

Using the first equation of motion

where;

Making acceleration (a) the subject of the formula; we have:

v - u = at

here;

Therefore, we can conclude that the magnitude of the car's acceleration is 0.8 m/s².
