Two masses, m1 = 25.0 kg and m2 = 45.0 kg, are attached by a massless rope over a massless pulley as shown above?The angle of the frictionless incline is 27.0 degrees . Assume that m2 starts at rest and falls a vertical distance of 3.00 m. Assume m1 also starts at rest and the rope remains taut.
a) Determine how much work is done by gravity on m2 as it falls.
b) Determine how much work is done by gravity on m1 as it moves up the incline.
c) Determine how much work is done by the normal force on m1 as it moves up the incline.
d) Determine the total kinetic energy of the two-mass system after m2 has fallen a vertical distance of 3.00 m.
e) Determine how much work the tension in the rope does on m1 as it moves up the incline.
