HURRYY PLESSEE A dog with a mass of 6 kg sits on top of a staircase 5 meters high. What is the dog's gravitational potential energy?

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called

Asap and show ! a 14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.

The number of passengers who arrive at the platform of a subway station for the 10 am train is a random variable with a mean of 120 and a variance of 16. find the lower bound of the probability that there will be between 100 and 140 passengers (round off to second decimal place).
