At what speed does a body weighing 4 kg move if its impulse is 20 kg * m / s

Given:

m = 4 kilograms is the mass of a moving body;

P = 20 kilograms * meter / second – the impulse of a moving body.

It is required to determine v (meter / second) – the speed of a moving body.

To find the speed of a body, you need to use the following formula:

P = m * v, hence:

v = P / m = 20/4 = 5 meters per second.

Answer: the speed of the body is 5 meters per second.
