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= 1 s?

A 25.0-kg box is released at the top of a frictionless ramp that is inclined at an angle of 35.0◦ with the horizontal. The box slides 1.50 m down the ramp before you catch it and bring it to a stop in 0.400 m. Assuming you pushed on the box with a constant force that was parallel to the ramp as you caught it, what was the magnitude of the force you exerted on the box to bring it to...

You push a crate of mass m up a ramp inclined at an angle A with a force parallel to the ramp but of varying magnitude. The coefficient of friction between the crate and ramp is u, and the speed of the crate, which starts from rest, is v at the end of the ramp of length d. a) Use the work-energy theorem to find the work done by the non-constant force in moving the crate up the ramp. b)...

One game at the amusement park has you push a puck up a long, frictionless ramp. You win a stuffed animal if the puck, at its highest point, comes to within 10 cm of the end of the ramp without going off. You give the puck a push, releasing it with a speed of 5.0 m/s when it is 8.7 m from the end of the ramp. The puck's speed after traveling 3.0 m is 4.0 m/s How far is...

A man pulls a 101.0 N crate up a frictionless ramp that is inclined at 0.9768 rad above the horizontal, starting at the bottom and going all the way to the top. The ramp is 5.143 m high, and the pulling force is parallel to the surface of the ramp. Assuming that the crate moves at a constant speed, calculate how much work did the man did on the crate. NOTE: Be sure to include units. W

A 9.00-kg block of ice, released from rest at the top of a 1.44-m-long frictionless ramp, slides downhill, reaching a speed of 2.88 m/s at the bottom. the angle between the ramp and the horizontal is 17.1 degrees. What would be the speed of the ice at the bottom if the motion were opposed by a constant friction force of 10.8 N parallel to the surface of the ramp? v=?

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...
