A student is skateboarding down a ramp that is 7.82 m long and inclined at 15.5° with respect to the horizontal. The initial speed of the skateboarder at the top of the ramp is 3.86 m/s. Neglect friction and find the speed at the bottom of the ramp.
A 5.00-kg package slides 2.60 m down a long ramp that is inclined at 25.0 ∘ below the horizontal. The coefficient of kinetic friction between the package and the ramp is μk = 0.370. A)Calculate the work done on the package by friction. B)Calculate the work done on the package by gravity. C)Calculate the work done on the package by the normal force. D)Calculate the total work done on the package. E)If the package has a speed of 2.60 m/s...
A 9.00 meter long ramp is inclined at an angle of 6.00 above horizontal. A 7 kg box is given an intial push at the bottom of the ramp so that when it gets to the top it stops. The coefficient of kinetic friction between the box and the ramp is .230 a) what is the initial speed of the box just as it is pushed. (The answer is 7.68 m/s, but I can't seem to set it up properly...
The skateboarder in the drawing starts down the left side of the ramp with an initial speed of 5.4 m/s. Neglect nonconservative forces, such as friction and air resistance, and find the height h of the highest point reached by the skateboarder on the right side of the ramp
A car (initially at rest) slides down a smooth, 30 m long ramp (neglect friction on the ramp) that is inclined at 6 deg. from the horizontal. At the bottom of the ramp, this car hits a second, identical car that is also initially at rest on a horizontal road. The effective coefficient of friction for the cars on the road is 0.6. How far will the cars roll after the crash before stopping?
