A girl pushes herself up a steep ramp in her wheelchair. She gains a vertical distance of 25.8 m when she reaches the top of the ramp. She turns around and coasts back down the ramp. If the combined mass of the girl and her wheelchair is 64.6 kg, what would be her coasting speed at the bottom of the ramp?
You MUST show all work starting with the formula (and rearrangement if needed). The formula must use symbols for formulas introduced in the VVS course. Next, you need to show the substitution of values into the formula, then the calculated answer. Remember to include units and use correct significant digits in your final answer. Responses only showing the final answer will receive a zero grade.

Regarding the previous question (Q21), what is the baseball's mechanical energy when it is a height of 8.0 m? Explain.
While playing baseball with your friends, you hit a 0.143 kg baseball off your bat and the ball goes straight up in the air. The ball reached a height of 10.0 m with a speed of 25.3 m/s. What is the mechanical energy at this height?
