if an object is moving with a velocity of 24 and has an acceleration of -4 square root how long will it take it to stop

Time, t = 8 seconds.

Explanation:

Given the following data;

Initial velocity = 24 m/s

Final velocity = 0 m/s (since the object is coming to a stop).

Acceleration = -4 m/s²

To find how long it will take the object to stop, we would use the first equation of motion;

Where;

Making time, t the subject of formula, we have;

Substituting into the equation, we have;

Time, t = 8 seconds.
