Problem 3 - To Be Handed In Name Student# Using a rope, you want to pull a 10 kg crate, up a frictionless 30° incline. At the bottom of the incline, the speed of the crate is 2.0 m/s and you pull with a force of 80 N, directed 10° above the incline. Knowing that the crate moves 8.0 m up the incline, what is its final speed? TO:30° Model - Make simplifying assumptions Visualize - Draw a picture; show...

An 7.9 kg crate is pulled 5.1 m up a 30° incline by a rope angled 18°above the incline. The tension in the rope is 130 N and the crate's coefficient of kinetic friction on the incline is 0.22 Wr. Wg.W'h= 630.-200,0 J What is the increase in thermal energy of the crate and incline? Express your answer using two significant figures AEth

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...

A crate of mass m1 = 11.4 kg is pulled by a massless rope up a 36.9° ramp. The rope passes over an ideal pulley and is attached to a hanging crate of mass m2 = 16.3 kg. The crates move 2.70 m, starting from rest. Find the final speed of the sliding crate if the incline is frictionless.

A crate of mass m1 = 11.4 kg is pulled by a
massless rope up a 36.9° ramp. The rope passes over an ideal pulley
and is attached to a hanging crate of mass m2 =
16.3 kg. The crates move 2.70 m, starting from rest. Find the final
speed of the sliding crate if the incline is frictionless.
Explanation
Since energy is conserved and nonconservative forces do no work,
mechanical energy is conserved. Let the y-axis point
straight upward....
