Solve the all parts of following question:
Question: Two masses, m1 = 25.0 kg and m2 = 45.0 kg, are attached by a mass less rope over a mass less pulley as shown above:( the image is an incline with m1 sliding up as m2 is lowered vertically by a pulley) The angle of the frictionless incline is 27.00.
Assume that m2 starts at rest and falls a vertical distance of 3.00 m. Assume m1also starts at rest and the rope remains taut.
Part A: Determine how much work is done by gravity on m2 as it falls.
Part B: Determine how much work is done by gravity on m1 as it moves up the incline.
Part C: Determine how much work is done by the normal force on m1 as it moves up the incline.
Part D: Determine the total kinetic energy of the two-mass system after m2 has fallen a vertical distance of 3.00 m.
Part E: Determine how much work the tension in the rope does on m1 as it moves up the incline.
I need help to determine how much work is done by gravity on m2 as it falls.
