Question 30
Easy

A marine research probe is winched vertically upwards from the seabed to a research platform.

Research probe being raised from seabed to platform

The probe has a mass of 8.50 kg.

During its ascent, the probe gains 374.85 J of gravitational potential energy.

Calculate the vertical distance, hhh, the probe was raised.

gravitational field strength = 9.8 N/kg

Use the equation:

ΔEp=m×g×Δh \Delta E_p = m \times g \times \Delta h ΔEp​=m×g×Δh
