A 2 kg ball is rolling down a hill at a constant speed of 4 m/s. How much kinetic energy does the ball have?

In a system, when potential energy decreases, then entropy also decreases. true false

Asatellite component is in the shape of a cube with 10cm edges, has an evenly distributed mass of 2 kg and one bolt hole at each of four corners. if the maximum predicted random vibration environment is 10 grms, what bolt size would be a good choice for restraint? what other factors might drive bolt size besides force/stress?

Discuss how the hardness or softness of the landing surface is related to the time required to stop the egg
