The table gives some measurements about a small meteorological sensor pod dropped from a high-altitude research drone:

Calculate the momentum of the sensor pod as it hits the ground. Give the unit.
State the equation linking gravitational potential energy (GPE), mass, ggg, and height.
Calculate the change in gravitational potential energy (GPE) when the sensor pod falls 450 m. (Assume g=9.8 m/s2g = 9.8 \text{ m/s}^2g=9.8 m/s2 or g=10 m/s2g = 10 \text{ m/s}^2g=10 m/s2).
State the kinetic energy (KE) of the sensor pod as it hits the ground, assuming no energy losses.
State the equation linking kinetic energy, mass, and speed.
Show that the speed of the sensor pod as it hits the ground, assuming no energy losses, would be approximately 94 m/s94 \text{ m/s}94 m/s.
Explain why the actual speed of the sensor pod as it hits the ground is much less than 94 m/s94 \text{ m/s}94 m/s.
