If you push an object with a force of 10 N for 5 seconds , you will change it’s momentum by:
2 N s
50 n s
2 N/s
50 N/s
Which of the following does the impulse-momentum equation implies? Check all that apply
The equation evaluates the change in momentum
It states that the change in momentum = impulse
In order to get the largest possible change in momentum, we use the equation to find the smallest impulse possible.
All of the above
