In the figure, a horizontal force F, of magnitude 20.0 N is applied to a 3.17 kg book as the book slides a distance d = 0.93 m up a frictionless ramp at angle e = 30°. (a) During the displacement, what is the net work done on the book by Fa, the gravitational force on the book, and the normal force on the book? (b) If the book has zero kinetic energy at the start of the displacement, what is its speed at the end of the displacement?

A horizontal force, F~ of 30 N is applied to a 2 kg object as it slides a distance d of1.7 m up a frictionless ramp at angle, θ = 35◦(a) During the displacement, what is the net work done on the object by the forces(horizontal force, F~ , gravitational force on the object and the normal force)acting on the object? (b) If the object was at rest at the start of the displacement, what is its speed atthe end of the displacement?

The figure shows three forces applied to a trunk that moves leftward by 3.37 m over a frictionless floor. The force magnitudes are F₁ = 5.11 N, F₂ = 8.70 N, and F3 = 2.75 N, and the indicated angle is 0 = 60°. (a) During the displacement, what is the net work done on the trunk by the three applied forces, the gravitational force, and the normal force? (b) Is there a net transfer of energy to or from the trunk? (c) Does the kinetic energy of the trunk increase or decrease? (a) Number i Units (b) (c) R F3 152⁰ 8

A tension force of 165 N inclined at 25.0° above the horizontal is used to pull a 39.0 kg storage crate a distance of 4.10 m on a rough surface. If the crate moves at a constant speed, find (a) the work done by the tension force and (b) the coefficient of kinetic friction between the crate and surface. (a) the work done by the tension force (in J)   (b) the coefficient of kinetic friction between the crate and surface
