Question 18

Medium

An emergency escape capsule on an offshore oil platform slides down a curved evacuation chute to sea level.

As the capsule slides down, the decrease in its gravitational potential energy is 9.996 kJ. The mass of the capsule is 120 kg. The gravitational field strength is 9.8 N/kg. Calculate the vertical height descended by the capsule.

[3]

As the capsule moves down the chute, its increase in kinetic energy is less than its decrease in gravitational potential energy. Explain why.

[2]

Different capsules (carrying different payloads or constructed with different surface materials) are observed to have different speeds at the bottom of the chute. Explain why.
