For the system of attached masses m1 & m2, which mass will have a higher acceleration?

• m1

• m2

• Both will have same acceleration because they're attached by a string

Two masses connected by a rope over a pulley are released, producing the bar graphs below. It took 0.80 seconds for Mass A to reach the top and Mass B to reach the bottom. What was the acceleration of Mass A?

• 5.12 m/s/s

• 3.20 m/s/s

• 2.05 m/s/s

• 1.28 m/s/s

An astronaut brings an Atwood Machine to the Moon, where the force of gravity is only one sixth of its strength on Earth. She places a 2.0 kg mass on one end of the rope, and a 3.0 kg mass on the other end of the rope. What will the astronaut observe when she releases the masses?

• The masses will accelerate faster than they would on Earth.

• The masses will accelerate more slowly than they would on Earth.

• The measured acceleration will be exactly the same as on Earth.

• There will be zero acceleration of the masses on the Moon.
