A) Halley's comet orbits the sun about every 75 years due to the gravitational force the sun provides. Compare the gravitational force between halley's Comet and the sun when the comet is at aphelion (its greatest distance from the sun) and d is about 4.5 x 10^10 m to the force at perihelion (or closest approach), where d is about 5.0 x 10^10 m. B) In part A, what is the comet's acceleration a) at aphelion? b) at perihelion? (M of the sun=1.99 x 10^30)

Please help!!!

area of focus

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.
