Answer 1

Answer #1

When a rock is sliding down the hill, the component of the weight down the hill does the work. As the rock is descending there must be a fall in the gravitational potential energy which results in a gain of kinetic energy.

b) weight, gravitational potential energy, kinetic energy

Some sliding rocks approach the base of a hill with a speed of 17.0 m/s . The hill rises at 42.0 ∘ above the horizontal and has coefficients of kinetic and static friction of 0.450 and 0.550, respectively, with these rocks. Start each part of your solution to this problem with a free-body diagram. Find the acceleration of the rocks as they slide up the hill. Once a rock reaches its highest point, will it stay there or slide down...

Now assume that the object is a solid sphere and instead of sliding down the hill, it ROLLS down the hill. It still starts from rest at a height of 1.4 m. Determine how fast it will be going at the bottom of the hill. Assume no thermal energy is generated and express your answer using appropriate mks units. Round your answer to the NEAREST THOUSANDTH
