1. Here are the densities and redii of planets in our solar system (in grams per cm ³ and km, respectively)

How much would you weigh on these different planets? 1 pound is equal to 0.453592 kg.

2. Consider an Atwood?s machine consisting of two masses connected by a string which is over a pulley, as shown in the picture.

a) Draw a free body diagram for both block A and block B.

b) Apply Newton?s second law to both block A and block B.

c) The mass of block A is 14 kg while the mass of block B is 6 kg, find the tension in the rope.

3. Consider a modified Atwood machine, with a mass sitting on a table connected by a string which stretches over a pulley connected to a hanging mass. Friction is ignored.

a) Draw a free body diagram for both block 1 and block 2. b) Apply Newton's second law to both block 1 and block 2. c) If the mass of block 2 is 20 kg while the mass of block 1 is 5 kg, find the tension in the rope.
