Please and thank you

You pull a sled across a horizontal frictionless patch of snow. If your pulling force is in the same direction as the sled's displacement and increases the kinetic energy of the sled by 35%, by what percentage would the sled's kinetic energy increase if the pulling force acted at an angle of 20° above the horizontal?

A sled is being pulled across a horizontal patch of snow. Friction is negligible. The pulling force points in the same direction as the sled's displacement, which is along the +x axis. As a result, the kinetic energy of the sled increases by 38 percent. By what percentage would the sled's kinetic energy have increased if this force had pointed 62 above the +x axis?

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 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 m.

You are pulling your sister on a sled across the flat field. Your sister and the sled have a total mass of 50 kg. You pull the sled, from starting to rest, with a constant force of 79 N at and angle of 45 degrees. What will the speed of the sled be when you reach 11.1 m from the start? If the coefficient of friction between the sled and a now is .15 what will the speed of the...

To pull a 36 kg crate across a horizontal frictionless floor, a worker applies a force of 230 N, directed 18° above the horizontal. As the crate moves 1.6 m, what work is done on the crate by (a) the worker's force, (b) the gravitational force on the crate, and (c) the normal force on the crate from the floor? (d) What is the total work done on the crate?

You are trying to drag a heavy sleeper-sofa across your floor. The sofa has a mass of 150 kg and the coefficient of static friction between the couch and the floor is 1.08. Being a bright physics student, you realize that you can make this easier by pulling upwards and forwards at the same time rather that just pulling the sofa forwards. If you pull on the sofa at an angle 32? above the horizontal how much force does it...
