A 0.038-kg pet lab mouse sits on a 0.35-kg air-track cart, as shown in (Figure 1) . The cart is at rest, as is a second cart with a mass of 0.25 kg. The lab mouse now jumps to the second cart. After the jump, the 0.35-kg cart has a speed of v1=0.86m/s.
What is the speed v2...
A 50.0-kg block is being pulled up a 16.0° slope by a force of 250 N that is parallel to the slope. The coefficient of kinetic friction between the block and the slope is 0.200. What is the acceleration of the block?
The Attempt at a...
I just reviewed it in my textbook and I was so wrong with the units.
Going back to part B I got,
I still don't understand how the velocity changes with each compression. would I solve for a new velocity and use the ΔKE to find the new velocity?
