- A 7.5 kg box initially at rest on a horizontal surface is pushed by a constant force of 34.2 N that is applied at angle 35.6° below the horizontal. As the box accelerates along the surface, it encounters a frictional force of 16.6 N. Using work-energy theorem, what is the speed of the box after it has traveled 4.75 m? vf Vi = 0 -d- O 7.50 m/s 5.93 m/s O 3.77 m/s 4.72 m/s mA small car and a semi-truck have the same total mechanical energy. Which of the following CANNOT be true? The car must be moving faster than the truck and the truck and car are at the same height. O The car is at a higher elevation and both the car and the truck are stationary. O The car is going the same speed as the truck and the car is at a higher elevation than the truck.

- 1) A constant horizontal force of F = 200.0 N pushes a crate of mass m = 25.0 kg, initially at rest, along a rough horizontal surface. The crate travels a total distance of 8.00 m, and the coefficient of kinetic friction between the crate and the surface is 0.250. a) What is the work done on the crate by the force F? b) How much does friction increase the internal energy of the crate-surface system ?An 8.5-kg block is pushed along a horizontal rough surface by a 40-N force inclined at 20° with the horizontal. The coefficient of friction between the surface and block is 0.35. If the block has an initial velocity of 3.6 m/s and the force does 200 J of work on the block, find: The total distance moved by the block. The final velocity of the block.= 13 kg, and m3 20 kg, respectively, are attached by strings over frictionless pulleys as indicated in the figure below.
