A 62.0 kg skier is moving at 6.90 m/s on a frictionless, horizontal, snow-covered plateau when she encounters a rough patch 4.80 m long. The coefficient of kinetic friction between this patch and her skis is 0.300. After crossing the rough patch and returning to friction-free snow, she skis down an icy, frictionless hill 2.50 m high. **Text:**How much internal energy was generated in crossing the rough patch?**Explanation:**This question prompts an exploration of the concept of internal energy in physics, specifically as it relates to motion over a rough surface. The generation of internal energy in this context typically involves the conversion of kinetic energy into thermal energy due to friction between surfaces. Understanding this process is crucial for studying energy conservation and transfer in physical systems.

In a circus performance, a monkey is strapped to a sled and both are given an initial speed of 5.14 m/s up a 22.1∘∘ inclined track. The combined mass of monkey and sled is 29 kg, and the coefficient of kinetic friction between sled and incline is 0.23. How far up the incline do the monkey and sled move?
Current Attempt in Progress The figure shows a cold package of hot dogs sliding rightward across a frictionless floor through a distance d = 22.0 cm while three forces act on the package. Two of them are horizontal and have the magnitudes F₁ = 8.0 N and F₂ = 2.0 N; the third is angled down by = 60.0° and has the magnitude F3 = 7.0 N.

A horizontal force of 80.0 N is applied to a 5.00 kg block as the block slides a distance of 0.800 m along a horizontal floor. The coefficient of kinetic friction between the floor and the block is 0.500. If the block is initially at rest, how fast is it moving at the end of the displacement?
A man (mass 45 kg) shoots himself out of a cannon straight upward with an initial velocity of 46 m/s towards a ledge 95 m above the cannon. There’s some air resistance occurring, and the man’s upward trajectory ends 6.0 meters below the ledge. A) What was the average force of frictional air resistance the man experienced during his upward motion? B) Assuming the same average air resistance on the way down, how fast will the man’s impact velocity be when he returns to the “ground” level of the cannon’s muzzle?

Your answer is partially correct. In the figure a block slides along a path that is without friction until the block reaches the section of length L = 0.66 m, which begins at height h = 1.1 m, on a ramp of angle 0 = 32°. In that section the coefficient of kinetic friction is 0.410. The block passes through point A with a speed of 8.4 m/s. If the block can reach point B (where the friction ends), what is its speed there, and if it cannot, what is its greatest height above A? Number i 8 6.46 Unit m/s

Small ice cubes, each of mass 7.15 g, slide down a frictionless track in a steady stream, as shown in the figure below. Starting from rest, each cube moves down through a net vertical distance of h = 1.50 m and leaves the bottom end of the track at an angle of 40.0° above the horizontal.
