Question 21

Medium

A base jumper leaps off a high cliff ledge.

As the base jumper descends, the decrease in their gravitational potential energy is $kJ25.725\text{ kJ}$ . The mass of the base jumper (including equipment) is $kg75\text{ kg}$ . The gravitational field strength is $N/kg9.8\text{ N/kg}$ . Calculate the change in vertical height of the base jumper.

[3]

As the base jumper falls, their increase in kinetic energy is less than their decrease in gravitational potential energy. Explain why.

[2]

Different base jumpers have different speeds after falling the same vertical distance. Explain why.
