An automated marine research glider is monitoring ocean currents.
The glider is fitted with photovoltaic film on its wings of total area 6.2 m26.2\text{ m}^26.2 m2. In clear daylight, each 1.0 m21.0\text{ m}^21.0 m2 of the film generates 0.150 kW0.150\text{ kW}0.150 kW of electrical power. Calculate the total electrical power generated by the photovoltaic film.
The glider is propelled by a buoyancy-engine thruster that produces a constant horizontal thrust force of 48 mN48\text{ mN}48 mN. Calculate the magnitude of the change in momentum of the glider when this thruster runs continuously for 75 minutes75\text{ minutes}75 minutes.
