statue slides down a ramp inclined at an angle ?=40∘, the curator pushes up, parallel to the ramp's surface, so that the crate does not accelerate. The statue slides a distance ?=5.0 m down the ramp, as shown in the figure, and the coefficient of kinetic friction ?k between the crate and the ramp is 0.54. Assume the that positive direction is down the ramp

A block slides down an incline of 30.0∘ to the horizontal at a constant velocity. What is the coefficient of dynamic friction between the block and the incline? Give your answer to 3 significant figures

kids decide to slide boxes down a long slide. the slide is inclined at 20 degrees and has a coefficient of kinetic friction equal to 0.200. the kids push a 45.0 kg box from the top of the slide so that the initial velocity is 2.25m/s. how far down the reap (in m) will the box go before it stops?

A skateboard with mass of 50kg is pulled without friction across the ground by a rope that makes an angle of 20 degrees with the horizontal. What force on the rope would be required to move the skateboard at a constant speed of 20 m/s?

what is the answer ?!

The coefficient of static friction between a rubber tire and dry pavement is about 0.800. Assume that a car's engine only turns the two rear wheels and that the weight of the car is uniformly distributed over all four wheels. What limit does the coefficient of static friction place on the time fmin required for a car to accelerate from rest to 50.0 mph (22.4 m/s)? Imin = How can friction accelerate a car forward when friction opposes motion?

A supermarket pushcart is being pushed at 45 degrees with respect to the horizontal from the starting point to the cashier, which is 25 feet away. The cart is 5kg, it contains 2 boxes of 10-1b flour and seven packs of half-kilogram sugar. The coefficient of friction between the wheels and the floor is 0.03. a. What force is required? b. How much force is required?

You are playing stuffleboard and you must slide your weighted disk 8m across the floor where it will come to rest on the target. You give it an initial push of 4 m/s but then it slides on its own to a stop. The disk is 0.8 kg. What is the coefficient of friction if your shot is perfect a bull's eye?

A 1,500-N crate is being pushed across a level floor at a constant speed by a force F of 370 N at an angle of 20.0° below the horizontal, as shown in the figure a below. F 20.0° / b 20.0° (a) What is the coefficient of kinetic friction between the crate and the floor? (Enter your answer to at least three decimal places.) 0.220 X Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error.

Hi, I really appreciate you taking the time to help me out! John places a coin on a horizontal turntable with a rubber surface. The coin is 28 cm from the center of the circular table. He notices that the coin just begins to slip when the table rotates at 45 rpm (revolutions per minute). What is the coefficient of static friction between the coin and turntable?
