What is the change in velocity (in m/s) if an impulse of 225 N acts on a 4.5 kg mass for 3.0 s?

To find the change in velocity, you can use the equation:

Change in velocity = Impulse / Mass

Given that the impulse is 225 N and the mass is 4.5 kg, we can substitute these values into the equation:

Change in velocity = 225 N / 4.5 kg

Simplifying this equation, we have:

Change in velocity = 50 m/s

Therefore, the change in velocity is 50 m/s.
