A person pulls a 11-kg toboggan for a distance of 3.5 m on a horizontal sheet of ice (frictionless) with a rope directed 25.0º above the horizontal snowy surface. The tension in the rope is 88 N. There is also a zephyr (soft gentle breeze) in the opposite direction of the motion applying a 11.0 N force.

(a) How much net work is done on the toboggan by ALL the forces acting on it?

(b) If the toboggan starts from rest, how fast is it moving after the 3.5 m distance?

(c) Use Dimensionality sense-making to check the expression you derive in part (b).

A person with mass m=80 kg is training for pushups. Assume that the distance between the shoulders and the feet is 1.5 m, and the center of mass is at 1 m from the feet. First, he is trying to do a normal pushup. Assuming only vertical forces, what is the force on the arms?After that proved to be too difficult, he tries a modified version, where his arms are on the kitchen counter instead (~92 cm from the ground),...

A person pulls a small trolley of mass 30 kg along a flat icy road with a rope. The rope exerts a tensile force of F = 300 N and makes an angle θ = 25o with the horizontal. The figure illustrates the situation but is not drawn to scale. Taking the acceleration due to gravity as g = 10 m s-2 in any calculations and round your answers to the nearest integer. You can assume that any frictional forces...

A block of mass m = 3.5 kg is on an inclined plane with a coefficient of friction μ1 = 0.23, at an initial height h = 0.46 m above the ground. The plane is inclined at an angle θ = 42°. The block is then compressed against a spring a distance Δx = 0.11 m from its equilibrium point (the spring has a spring constant of k1 = 39 N/m) and released. At the bottom of the inclined plane...

A man pulls a crate of mass 61.0 kg across a level floor. He pulls with a force of 180.0 N at an angle of 29.0° above the horizontal. When the crate is moving, the frictional force between the floor and the crate has a magnitude of 122.0 N. If the crate starts from rest, how fast will it be moving after the man has pulled it a distance of 2.50 m?
