PHYS 1301W Lecture 1: Gravitation

Find the tension in the rope of an Atwood machine that has a 40 kgmass hanging on
one side and a 60 kg mass on the other.

Two masses are connected by a light string passing over a light,frictionless pulley. The m1 = 5.00 kg object is released from restat a point 4.00 m above the floor, where the m2 = 3.35 kg objectrests.

(a) Determine the speed of each object when the two pass eachother.
_______________________________m/s

(b) Determine the speed of each object at the moment the 5.00 kgmass hits the floor.______________________ m/s

(c) How much higher does the 3.35 kg mass travel after the 5.00 kgmass hits the floor?_______________________m

What is the change in gravitational potential energy of a 10 kgmass that is carried from the surface of the earth to a distance of oneearth radius above the surface?
