Nicholas is at The Noah's Ark Amusement Park and preparing to ride on The Point of No Return racing slide.
At the top of the slide, Nicholas (m=72.6 kg) is 28.5 m above the ground.
a. Determine Nicholas' potential energy at the top of the slide.
b. Determine Nicholas's kinetic energy at the top of the slide.
c. Assuming negligible losses of energy between the top of the slide and his approach to the bottom of the
slide (h=0 m), determine Nicholas's total mechanical energy as he arrives at the bottom of the slide.
d. Determine Nicholas' potential energy as he arrives at the bottom of the slide.
e. Determine Nicholas' kinetic energy as he arrives at the bottom of the slide.
f. Determine Nicholas' speed as he arrives at the bottom of the slide.
