refer to picture.
A boy pulls his younger sister on a toboggan by a rope that makes an angle of 37.0° with the horizontal, as shown. The boy maintains a tension of 25.0 N in the rope and walks, on level ground, at a constant speed of 1.10 m/s. The combined mass of the girl and the toboggan is 30.0 kg. Determine a. the normal force exerted on the toboggan by the ground. the coefficient of kinetic friction between the...

A 65.0-kg boy and his 40.0-kg sister, both wearing roller blades, face each other at rest. The girl pushes the boy hard, sending him backwards with velocity 2.90 m/s towards the west. Ignore friction. (a) Describe the subsequent motion of the girl. (b) How much potential energy in the girls body is converted into mechanical energy of the boy-girl system? (c) Is the momentum of the boy-girl system conserved in the pushing-apart process? If so, explain how that is possible...

A factory worker pushes a 30.0 kg crate a distance of 4.5 m along a level floor at constant velocity by pushing downward at an angle of 30° below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.25. Part A What magnitude of force must the worker apply to move the crate at constant velocity? Part B How much work is done on the crate by this force when the crate is pushed a distance of 4.5 m? Part C How...

Problem 1: Work done by constant forces. A 500N force is pulling an 100-kg refrigerator across a horizontal surface. The force acts at an angle of 36.9 degress above the surface. The coefficient of kinetic friction us 0.200, and the refrigerator moves a distance od 10.00 m. Determine: a.The work done by all the forces acting on the refrigerator. b. The net work acting on the refrigerator. c. The velocity of the refrigerator at the end of the 10 m,...
