A 121 kg crate is sitting at the top of a ramp, which is inclined at an angle of 18 degrees with respect to the horizontal. The crate is a height 0.51 m from the ground, measured vertically from the ground to the crate. Someone gives the crate a quick shove to get it moving, after which it slides down the ramp without any further assistance. The coefficient of kinetic friction between the crate and the ramp is Hs = 0.23. How much time (in seconds) does it take for the crate to get to the base of the ramp?

A mover has to move a heavy sofa of mass 118 kg to the second floor of the house. He uses a rope to pull the sofa up a ramp from the first to the second floor. As he pulls the sofa he makes sure that the rope is parallel to the surface of the ramp which is at 30.0° to the horizontal. If friction between the sofa and the ramp is negligible, and the sofa has an acceleration of 0.700 m/s2, find the tension in the rope (in N). N
Two crates of fruit are released from the top of a ramp inclined at 30 degrees from the horizontal and 4.5 meter long. The two crates consist of an apple crate of mass 20 kg that is placed in front of a watermelon crate of mass 80 kg. The apple crate has a coefficient of friction of 0.20 while the watermelon crate has a coefficient of friction of 0.15. How long does it take the apple crate to reach the bottom of the incline if it needs to travel a distance of 4.5 meters?
The figure shows a box of dirty money (mass m₁ = 3.5 kg) on a frictionless plane inclined at angle 0₁ = 34°. The box is connected via a cord of negligible mass to a box of laundered money (mass m₂ = 1.6 kg) on a frictionless plane inclined at angle 02 = 68°. The pulley is frictionless and has negligible mass. What is the tension in the cord? Number Units M²1 m2 02/

In a movie, a stuntman places himself on the vertical front of a truck as the truck accelerates. The coefficient of static friction between the stuntman and the truck is 0.370. The stuntman is not standing on anything but can “stick” to the front of the truck as long as the truck continues to accelerate. What minimum forward acceleration will keep the stuntman on the front of the truck?
The drawing shows a 29.2-kg crate that is initially at rest. Note that the view is one looking down on the top of the crate. Two forces, F and are applied to the crate, and it begins to move. The coefficient of kinetic friction between the crate and the floor is k = 0.348. Determine the (a) magnitude and (b) direction (relative to the x axis) of the acceleration of the crate.
