Arock is sliding down a hill. assume that the hill is 20 meters high and the rock has a mass of 1,000 kilograms. if the rock started at the top of the hill with no initial speed, how much is its kinetic energy when it reaches the bottom of the hill? use g=10 m/s2. give the answer in kilojoules.

Aphysics student stands at the top of a hill that has an elevation of 56 meters. he throws a rock and it goes up into the air and then falls back past him and lands on the ground below. the path of the rock can be modeled by the equation y=0.04x^2+1.3x+56 where x is the horizontal distance, in meters, from the starting point on the top of the hill and y is the height, in meters, of the rock above the ground.

During a rockslide, a 570 kg rock slides from rest down a hillside that is 700 m along the slope and 210 m high. the coefficient of kinetic friction between the rock and the hill surface is 0.13. (a) if the gravitational potential energy u of the rock-earth system is zero at the bottom of the hill, what is the value of u just before the slide? (b) how much energy is transferred to thermal energy during the slide? (c) what is the kinetic energy of the rock as it reaches the bottom of the hill? (d) what is its speed then?

A28-kg rock approaches the foot of a hill with a speed of 15 m/s. this hill slopes upward at a constant angle of 40.0∘ above the horizontal. the coefficients of static and kinetic friction between the hill and the rock are 0.75 and 0.20, respectively. (a) use energy conservation to find the maximum height above the foot of the hill reached by the rock. (b) will the rock remain at rest at its highest point, or will it slide back down the hill? (c) if the rock does slide back down, find its speed when it returns to the bottom of the hill.
