Question 1 1. Average acceleration is calculated by:

Question 2 2. Consider a man walking around a house in a rectangle pattern. He walks 70 feet across the front, 30 feet along the side, 70 feet along the back, and 30 feet along the other side to bring him back to where he began. What is the displacement of the man walking around the house?

Question 3 3. A planet is orbiting a star in a perfect circle. It has a velocity of 4x10^4 m/s, a mass of 3 x 10^24 kg. If at a particular moment it's orbiting at a radius of 2 x 10^11 meters, how much angular momentum does it have?

Question 4 4. Consider a man walking around a house in a rectangle pattern. He walks 70 feet across the front, 30 feet along the side, 70 feet along the back, and 30 feet along the other side to bring him back to where he began. If it took the man 2 minutes to complete the walk, what was his speed?
