Jen, cruising along on her moped at 12.5m/s, suddenly runs out of gas at the base of a hill.
a. If she and the moped have a mass of 150kg combined, what is their kinetic energy?
b. At that speed, how high of a hill could she climb?
c. If the hill in front of her is 15m high, how much work would she have to do to get to the top?

Help please!!!

He viscosities of several liquids are being compared. all the liquids are poured down a slope with equal path lengths. the liquid with the highest viscosity will

Why are graphs useful when interpreting data

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
