- sadasdasdasdaskids 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 1.2 kg crate slides down a 300 ramp with a height of 2.77. The crate has a speed of 2.90 m/s at the bottom of the ramp. The ramp is 5.8 m long. What is coefficient of kinetic friction?
- A hockey puck with mass 0.163 kg is pushed across the ice with a constant force of 0.37 N. The coefficient of kinetic friction between the puck and the ice is 0.13. After a distance of 1.3 m, what is the puck's speed in m/s?Time left 0:20:32 An amusement park in Dubai has a ramp which is frictionless. A child drops a smooth object and it slides down the ramp and comes down through a height 4 m. What distance is necessary to stop the object on the flat track if the coefficient of friction is 0.4? h. Answer:You are driving through the Ouachita Mountains at 12m/s. You see a maple-leaf oak (Quercus acerifolia) crossing the road and hit the brakes, 20m away. The coefficient of kinetic friction between your tires and the road is μ_k = 0.7. Will you strike this endangered broadleaf? Justify your answer with a calculation.Your final answer should be the distance you will travel before coming to a stop.
- A car has a mass of 1520 kg. While traveling at 25 m/s, the driver applies the brakes to stop the car on a wet surface with a 0.40 coefficient of friction. How far does the car travel before stopping?At Ted's request, Bill pushes the pizza box across the granite countertop towards Ted. When the box leaves Bill's hand it is sliding at 2.60 m/s. The box comes to rest over a distance of 110 cm. What is the coefficient of kinetic friction, uk, between the pizza box and the countertop? (Ignore air drag.)You are quite excited with the lesson in friction that you learned in Physics 1A that you decide to measure the coefficient of kinetic friction of surfaces. You try your idea on a glass surface and a glass cup (mass = 0.15 kg). You set the glass cup moving with an initial speed of 2.8 m/s. After travelling a length of 1 m, it stopped. What then is the coefficient of kinetic friction of the glass-glass surfaces?
