The figure shows a cord attached to a cart that can slide along a frictionless horizontal rail aligned along an x axis. The left end of the cord is pulled over a pulley, of negligible mass and friction and at cord height h = 1.2 m, so the cart slides from x1 = 4.0 m to x2 = 2.0 m. During the move, the tension in the cord is a constant 25.0 N. What is the change in the kinetic energy of the cart during the move?

A box with mass m = 1.5 kg is sliding with a speed of 4.0 m/s on a horizontal surface. When at x = 0, it encounters a rough section where the frictional force varies according to the equation f(x)=−(10+40x)f(x)=−(10+40x) where ff is in newtons and x is in meters. How far does this box slide before stopping?
A water slide is constructed so that swimmers, starting from rest at the top of the slide, leave the end of the slide traveling horizontally. As the drawing shows, one person hits the water 5.00 m from the end of the slide in a time of 0.627 s after leaving the slide. Ignore friction and air resistance, find the height H in the drawing.
A small block slides down a frictionless track whose shape is described by y = (x^2) /d for x<0 and by y = -(x^2)/d for x>0. The value of d = 3.16m, and x and y are measured in meters as usual. The block starts at x = 0, and is given a push to the left with an initial speed of 2.60 m/s, so it starts sliding up the track to the left. At what value of x will the block reverse direction and start sliding back down? 0.34 m -0.34 m -1.04 m 1.04 m
Using a simple pulley and rope system, a crewman on an Arctic expedition is trying to lower a crate of mass ?1=5.13 kg to the bottom of a steep ravine of height ?=22.5 m. The crewman of mass ?2=60.9 kg is walking while holding the rope, being careful to lower the crate at a constant speed of ?0=1.50 m/s. Unfortunately, when the crate reaches a point ℎ=12.5 m above the ground, the crewman steps on a slick patch of ice and slips. The crate immediately accelerates toward the ground, dragging the hapless crewman across the ice and toward the edge of the cliff. Assuming the ice is perfectly slick, so that there is no friction between the crewman and the ice once he slips and falls down, at what speed ?1 will the crate hit the ground? Assume also that the rope is long enough to allow the crate to hit the ground before the crewman slides over the side of the cliff, and that the pulley is frictionless. ?1=. m/s At what speed ?2 will the crewman hit the bottom of the ravine? Assume no…
A small block slides down a frictionless track whose shape is described by y = (x^2) /d for x<0 and by y = -(x^2)/d for x>0. The value of d is 4.74 m, and x and y are measured in meters as usual. Now suppose the blocks starts on the track at x = 2.39 m. The block is given a push to the left and begins to slide up the track, eventually reaching its maximum height at x = 0, at which point it turns around and begins sliding down. What was its initial speed in this case? 6.74 m/s 4.86 m/s 3.44 m/s 4.98 m/s
A car of mass m = 1100 kg is traveling down a θ = 14 degree incline. When the car's speed is v0 = 13 m/s, a mechanical failure causes all four of its brakes to lock. The coefficient of kinetic friction between the tires and road is μk = 0.45. Calculate the distance the car travels down the hill L in meters until it comes to a stop at the end
The skateboarder in the drawing starts down the left side of the ramp with an initial speed of 6.3 ft/s. If nonconservative forces, such as kinetic friction and air resistance, are negligible, what would be the height "h" of the highest point (in meters) reached by the skateboarder on the right side of the ramp?
a block is released from rest at height d = 40 cm and slides down a frictionless ramp and onto a first plateau, which has length d and where the coefficient of kinetic friction is 0.50. If the block is still moving, it then slides down a second frictionless ramp through height d/2 and onto a lower plateau, which has length d/2 and where the coefficient of kinetic friction is again 0.50. If the block is still moving, it then slides up a frictionless ramp until it (momentarily) stops. Where does the block stop? If its final stop is on a plateau, state which one and give the distance L from the left edge of that plateau. If the block reaches the ramp, give the height H above the lower plateau where it momentarily stops.
A block of mass m = 2kg slides across a flat surface with friction present. If the block starts with a speed v = 3m/s, and slides 2.3m before coming to rest, what was the magnitude of the constant friction force that brought it to a stop? Group of answer choices 5.45 N 3.91 N 19.6 N 11.2 N
