4) You run to the end of the hallway and enter a large room. Your kitty is on the opposite side of the room! You must slide down a 30 ramp to reach your kitty cat. You have an initial velocity of 2 ft/s and a mass of 80 kg. Determine your velocity after sliding down the ramp for 4.5s if the coefficient of kinetic friction between your shoes and the floor is 0.22

You have been assigned to design a package moving system as
shown in the figure. Boxes start at the top of the ramp with some
initial velocity. They slide down a nearly frictionless part of the
ramp and then are stopped due to friction on the horizontal part of
the ramp. The ramp has a height of h = 2.0 m, the initial velocity
of the boxes is vi = 2.4 m/s, and the distance the box
should travel before...

1. You have one last large 50 kg crate to move from your apt to your car and your inconsiderate roommate took the cart with him. So in order to move the crate, you tie a string to it and pull at an angle of 30° above the horizontal such that you move the crate along at a relatively constant speed. The coefficient of kinetic friction between the floor and the crate is 0.2 and the coefficient of static friction...

You are rearranging the furniture in your living room. In doing so, you push a 33 kg sofa to the left a total distance of 3 m and then you push it back to the right a distance of 1 m. The coefficient of kinetic friction between the sofa and the hardwood floor is 0.2. What is the work done by friction in moving the sofa? Express your answer in joules to one significant figure. Suppose that you had instead...

A)
You pull on a large box using a rope as in (Figure 1), except
the rope is at an angle of 15.0∘ below the horizontal. The
weight of the box is 325 N , and the coefficient of kinetic
friction between the box and the floor is 0.270. What must be the
tension in the rope to make the box move at a constant
velocity?
Express your answer with the appropriate units..
B) What is the normal force that...

A thin ring of outer radius, ro, inner radius, ri, and weight, W, with an initial counterclockwise angular velocity, wo, is placed in the corner formed by the floor and a vertical wall. Denoting the coefficient of kinetic friction between the thin ring and the wall and the floor as lk, derive an expression for the time required for the thin ring to...

You are a member of an alpine rescue team and must get a box of supplies, with mass 2.40 kg , up an incline of constant slope angle 30.0 ∘ so that it reaches a stranded skier who is a vertical distance 3.40 m above the bottom of the incline. There is some friction present; the kinetic coefficient of friction is 6.00×10−2. Since you can't walk up the incline, you give the box a push that gives it an initial...
