Ok, so let me rethink this. If the initial direction of motion of man + box is set to be positive, then am I simply going to be adding two positive quantities in the initial calculation of the momentum?
If the final velocity of the box is 5 m / s with respect to the ground, and I am...
Hello,
I am having trouble understanding this short problem from a Kaplan SAT II prep book. Here it is:
A 60 kg man holding a 20 kg box rides on a skateboard at a speed of 7 m/s. He throws the box behind him, giving it a velocity of 5 m/s. with respect to the ground. What is his velocity...
