Q1.
The photograph below shows a theme park ride called AquaShute.
Riders of the AquaShute sit on a sled and move down a slide.
The decrease in gravitational potential energy of one rider on the slide was 8.33 kJ.
The rider moved through a vertical height of 17.0 m.
gravitational field strength = 9.8 N/kg
Calculate the mass of the rider.

Mass of rider = _______________ kg (4)
-
Ep=m×g×h
8330=m×9.8×17.0
m= 8330/9.8×17.0
m= 8330/166.6
=50.0kg
