A block (6 kg) starts from rest and slides down a frictionless ramp #1 of height 6 m. The block then slides a horizontal distance of 1 m on a rough surface with kinetic coefficient of friction μk = 0.5. Next, it slides back up another frictionless ramp #2. Find the following numerical energy values: 1.Initial gravitational potential energy on Ramp #1: U1G = J 2.Kinetic energy at bottom of Ramp #1 before traveling across the rough surface: K =...

A 6.7 Kg block is released from rest at the point A shown in the picture below, slides down the hill through the points B and C, where it eventually comes to rest. In moving from A to B friction does -47 J of work on the block. In moving from B to C friction does another -33 J of work. (a) How much work does the normal force do on the block as it moves from A to C?...

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

A 1250 kg car drives up a hill that is 16.2 m high. During the drive, two nonconservative forces do work on the car: (i) the force of friction, and (ii) the force generated by the car's engine. The work done by friction is -2.91 times 10^5 J; the work done by the engine is 6.64 times 10^5 J. Find the change in the car's kinetic energy from the bottom of the hill to the top of the hill.

A m= 5.0 kg block slides on a flat, smooth track with an
initial speed of vi= 6 m/s. The block slides down a rough incline
that has a vertical height of h = 4 m onto another flat, smooth
track. The block’s final speed is vf= 10 m/s. How much energy is
lost to friction on the block as it slid down the incline?
