(a) As the lander is descending, if the pilot decides to shut down the engine when the lander is at a height of 2.1 m, (this may not be a safe height to shut down the engine) and the velocity of the lander (relative to the surface of the planet) is 1.2 m/s what will be velocity of the lander at impact

this is a good question! i'll do some research and come back when i have the answer!

1/0.14nm = 10^10/1.4 a lot

magnified images possible images can be real = projected onto a screen

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
