Question #1
Recall that weight is a force and is equal to m*g, where g is the acceleration due to gravity exerted by the Earth near the Earth's surface. The acceleration due to gravity exerted by the moon near the moon's surface is 16.6% that of Earth. What is the weight (in N) of a person with a mass of 63.6 kg on the moon?_____
Question #2
Using the pulley system below, if m1=3.5 kg and m2 = 8.4 kg, what is the acceleration of m2 in m/s/s? Use up as the positive direction for m2.
Hint: Draw force diagrams.
Hint: Derive two equations with two unknowns.
