1. A box that weighs 66.2 N on Jupiter is taken to Pluto. The weight of the box on Pluto will be ____. (acceleration on pluto is 0.42)

**Would you find the mass first?**

2. The hand in the image above is applying a force to the right of 69 newtons. The surface that the blocks are sliding across is frictionless. If the mass of block A is 11 kg and the mass of block B is 31 kg, the acceleration of block B is ____.

**I tried subtracting the two masses and doing them separate to find acceleration but it did not work.**

3. student stands on a bathroom scale in an elevator at rest on the 64th floor of a building. The scale reads 836 N. As the elevator moves up, the scale reading increases to 960 N, then decreases back to 836 N. The acceleration of the elevator is ___.

**Would you find the mass? If so, how? Would the two 836's cancel each other out leaving only 960? Is that the net force?**

4. On Saturday, October 23, 2010, Cain Velasquez won the UFC heavyweight championship. Velasquez has a mass of 111 kg. Sometime later, Velasquez punches Mr. Tubbs in the face for giving his students too much homework. If Mr. Tubbs has a mass of 93 kg and Velasquez punches Mr. Tubbs with a force of 596.3 newtons, then Mr. Tubbs' face exerts a force of _____

on Velasquez's fist.

**How does the total force come into play? Is there info that isnt relevant?**

5. A force of +40.0 N accelerates a 5.0 kg block at 6.0 m/s2 along a horizontal surface. The frictional force is ___.

**What does the 40 N have to do with anything? How do I incorporate that into the problem?**
