Answer:
Student’s(50 kg) gravitational potential energy if the cliff is 80 m high = 39.2 kJ
Explanation:
Potential energy is given by the expression, PE =mgh, m is the mass, g is the acceleration due to gravity value and h is the height.
Here mass of student, m = 50 kilogram
Height of cliff , h = 80 meter
Acceleration due to gravity = [tex]9.8m/s^2[/tex]
Potential energy, PE = 50 * 9.8 * 80 = 39200 J
= 39.2 kJ
Student’s(50 kg) gravitational potential energy if the cliff is 80 m high = 39.2 kJ
