4. A small child gives a plastic frog a big push at the bottom of a slippery (frictionless) 2.0-m-long ramp inclined at 35o to the horizontal, starting it with a speed of 5.6 m/s. What is the frog's speed as it flies off the top of the ramp?

    Sam needs to push a 5.0 kg package up a frictionless ramp that is (8/3) m long and inclined 20◦above the horizontal. Sam pushes with a force that is parallel to the incline.•The initial speed of the package is 0 m/s and the final speed at the top of the ramp is 0 m/s.•The package accelerates parallel to the ramp with a magnitude of a(t) =−4(m/s^3)t+ 4(m/s^2). What is the instantaneous power that Sam applies to the package at t=...

    A child slides down a snow‑covered slope on a sled. At the top of the slope, her mother gives her a push to start her off with a speed of 0.70 m/s. The frictional force acting on the sled is one‑fifth of the combined weight of the child and the sled. If she travels for a distance of 24.5 m and her speed at the bottom is 4.25 m/s, calculate the angle that the slope makes with the horizontal.

    You are working for a shipping company. Your job is to stand at the bottom of a 8.0-m-long ramp that is inclined at 37∘ above the horizontal. You grab packages off a conveyor belt and propel them up the ramp. The coefficient of kinetic friction between the packages and the ramp is μk=0.30. What speed do you need to give a package at the bottom of the ramp so that it has zero speed at the top of the ramp?...

    Constants Learning Goal: To practice Problem-Solving Strategy 6.1 Work and Kinetic Energy. Your cat Goldie (mass 7.90 kg ) is trying to make it to the top of a frictionless ramp 7.640 m long and inclined 33.0 ∘ above the horizontal. Since Goldie can’t get any traction on the ramp, you push her up the entire length of the ramp by exerting a constant 41.00 N force parallel to the ramp (there is a set of stairs alongside the frictionless...

    A 5.80-kg box sits at rest at the bottom of a ramp that is 8.20 m long and that is inclined at 40.0 ∘ above the horizontal. The coefficient of kinetic friction is μk = 0.40, and the coefficient of static friction is μs = 0.43. What constant force F , applied parallel to the surface of the ramp, is required to push the box to the top of the ramp in a time of 4.00 s ? Express your...

    You do a physics lab experiment on another planet. A small block is released from rest at the top of a long frictionless ramp that is inclined at an angle of 36.9° above the horizontal. You measure that a small block travels a distance 10.0 m down the incline in 5.80 s. What is the value of g, the acceleration due to gravity on this planet?

    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...
