What statement best decribes the relationship between the work done by Katrina and the kinetic energy?

A 20 degree incline is shown with a 18 Kg block that is given an initial velocity 4 m/s down the incline. If the coefficient of kinetic friction is 0.5 calculate the acceleration of the block. 18 Kg 3.35 1.25 7.96 up the incline 7.96 down the incline 1.25 up the incline down the incline down the incline 4 m/s 20

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) For the 22.0 cm displacement, what is the net work done on the package by the three applied forces, the gravitational force on the package, and the normal force on the package? (b) If the package has a mass of 4.0 kg and an initial kinetic energy of 0, what is its speed (in m/s) at the end of the displacement? (a) Number i (b) Number Units Units Hot Dogs Ve F F d

A package is projected 10 m upward on a 15 ° inclined plane so that it reaches the top of the plane with zero velocity. Knowing that the coefficient of kinetic friction between the package and the incline is 0.15, determine the speed of the package when it returns to its original position.

WE-4 A 3.00kg block is initially sliding to the right on P (N) 20 a frictionless surface at 7.00m/s. Force P is directed to the left and is applied to the block continuously starting at the initial position as shown below. The magnitude of P varies as shown in the graph to the right.

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? Please answer the question on paper. I do not understand when it is typed out. Thank you

A block is being pushed with a force of 10 N at a downward angle of 60 degrees below the horizontal.   The coefficient of static friction is 0.6.  Is this enough to make a block of 800 g move?

At the start of a race, a four-man bobsled team pushes their sled as fast as they can along a 50 m flat starting stretch. The net force that the four men together apply to the 325 kg bobsled is 80.093 N directed at 15 degrees below the horizontal. As they push, 60 N of kinetic friction opposes them. What is the speed of the sled right before the team jumps on the sled?

A 18-kg sled is being pulled along the horizontal snow-covered ground by a horizontal force of 24 N. Starting from rest, the sled attains a speed of 1.7 m/s in 9.1 m. Find the coefficient of kinetic friction between the runners of the sled and the snow. Number i Units
