Question 13 13 pts A box of mass 0.8 kg is being pulled up a slope that is inclined by 60° compared to the horizontal. The tension in the rope pulling the box is 40 N and the rope is parallel to the incline. The slope is NOT frictionless and the coefficient of kinetic friction between the box and the slope is 0.35. Round off your answers to two decimal places. (a) What is the magnitude of the weight of...

An 8.3 kg crate is pulled 5.1 m up a 30 degree incline by a rope angled 19 degree above the incline. The tension in the rope is 100 N and the crate's coefficient of kinetic friction on the incline is 0.23. How much work is done by tension, by gravity, and by the normal force? Express your answers using two significant figures. Enter your answers numerically separated by commas. What is the increase in thermal energy of the crate...

Shortly after the start of a dogsled race, you find yourself pulling your supplies across the snow (those $#@*&%^*& sled dogs are in BIG trouble). You apply a force of 300 N to a rope that is attached to the front box at an angle of 20 degrees above the horizontal. Mass of the front box M=40Kg, mass of the black box m=30kg, and there is no friction between the boxes and the snow. A)Draw a free-body diagram of each...

You pull a your friend along in a sled (combined mass is 65 kg), by pulling the rope at an upward angle of 20 degrees with respect to the ground with enough force to keep the sled moving at a constant velocity of <3,0, 0> m/s. The coefficient of kinetic friction between the ground and the sled is 0.15. (a) Draw a force diagram for the friend/sled system. (b) Once you get to constant velocity, you pull the sled 15...

1. A roller coaster has a 300 kg car. Assume the track is frictionless. a) The car starts at a speed 20 m/s on a horizontal track. It then goes through a circular loop. What is the speed of the car when it is at the top of the loop, h = 10 m above the horizontal track? b) What is the normal force applied from the track at the point? Does this force point upward or downward? Assume the...

A hammer of mass M is moving at speed v_0 when it strikes a nail of negligible mass that is stuck in a wooden block. The hammer is observed to drive the nail a distance L deeper into the block. Find the work W done on the hammer by the nail. Express your answer as a function of F and L, where F is the force the nail exerts on the hammer. Don't forget to consider the sign of your...

A)
b) using the information from the previous question what is the
net work done on the block as it is displaced?
A block of mass M is pulled over a rough horizontal surface. The block has a coefficient of kinetic friction with the surface of u. The block is subject to the normal force, the friction force, the force of gravity, and a force from a rope of magnitude T which pulls up and to the right at an...
