A crate of mass m1 on a frictionless inclined plane is attached to another crate of mass m2 by a massless rope. The rope passes over an ideal pulley so the mass m2 is suspended in air. The plane is inclined at an angle ? = 36.9ยฐ. Use conservation of energy to find how fast crate m2 is moving after m1 has traveled a distance of 1.4 m along the incline, starting from rest. The mass of m1 is 13.0 kg and the mass of m2 is 23.4 kg.

-A crate of mass m (=30 kg) is placed at rest on a (frictionless)inclined plane, which has an angle (= 60o) above horizontal.

a)How long would it take the crate to slide 8 m down theincline?

b)If the crate were kept from sliding by a rope pulling parallel tothe incline, what would the size of the tension be?

1. a 50 N crate is pulled up a 5-m inclined plane by a worker at aconstant velocity. if the plane is inclined at 37 degrees to thehorizontal and there exists a constant frictional force of 10Nbetween the crate and the surface what is the force applied by theworker?

2. a 20-N crate starting at rest slides down a rough 5.0m long rampinclined at 25 degrees with the horizontal. 20J of energy is lostto friction. what will be the speed of the crate at the bottom ofthe incline?
