3. A 500 g block of wood is at the top of a ramp. It slides down the ramp and collides with a 750 g cart that is at rest at the bottom of the ramp. After the collision, the cart is traveling at 2.55 m/s and the block is at rest. How tall is the ramp?

In one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
