Using SI units, calculate the change in potential energy of a 150-lb person riding the 15-ft-long uphill portion of a water slide (as described in Problem P3.10). The change in potential energy is defined as is the change in vertical height. The uphill portion of the slide is set at an angle of 45o.
Reference: Problem P3.10
Uphill water slides are becoming more popular at large water parks. Uphill speeds of riders can reach 19 ft/s. Express this speed in mph.
