4. A crate is pulled up a ramp a distance of 20 m with a force of F = [800, 500]. The crate ends up 2 m higher above the ground than where it started.

4. A crate is pulled up a ramp a distance of 20 m with a force of F = [800, 500]. The crate ends up 2 m higher above the ground than where it started. a. (APP - 4 marks) Find the force applied on the crate that moves the crate up the ramp and the force that is perpendicular to the ramp that lifts the crate up off the ramp. b. (APP - 2 marks) Find the work done moving the crate up the ramp and the work done lifting the crate 2 m above the ground.

A worker pushing a 35.0 kg wooden crate at a constant speed for 12.0 m along a woodfloor does 350 J of work by applying a constant horizontal force of magnitudeF on the crate.(a) Determine the value of F.(b) If the worker now applies a force greater than F, describe the subsequent motion ofthe crate.(c) Describe what would happen to the crate if the applied force is less than F.

A man pushes an 80-N crate a distance of 5.0 m upward along a frictionless slope that makes an angle of 30° with the horizontal. His force is parallel to the slope. If the speed of the crate decreases at a rate of 1.5 m/s2, then the work done by the man is:

A 21-N crate starting at rest slides down a rough 4-m long ramp, inclined at 25° with the horizontal. 15 J of energy is lost to friction. What will be the speed of the crate at the bottom of the incline?Select one:a.4.4 m/sb.1.4 m/sc.9.4 m/sd.3.1 m/se.​19.1 m/s

A rocket is attached to a crate with a combined mass of 1330 kg. The crate is launched with 242 N of thrust down a frictionless icy hill sloped at 16.4° from the horizontal. What is the magnitude of acceleration of the crate while it travels down the hill?
