You and your run towards each other. At time zero, you are at x = 0 and your friend is at x = 30 m. Your speed is 5 m/s and your friend's speed is 2.5 m/s. Draw a graph of x vs t that shows you vs your friend, making sure that the slopes reflect that your speed is twice your friend's speed. From the graph, estimate when and where you and your friend will meet.

You and your fellow astronaut are floating in space right next to each other initially at rest. You have a mass of 68 kg and your friend has a mass of 87 kg. You get into an altercation and your friend pushes you. After the push you are traveling at 2.5 m/s in the +x direction. What is your fellow astronauts velocity after the push? Express your answer in meters per second and round to one decimal place.

You throw a baseball directly upward at time t = 0 at an initial speed of 14.7 m/s. What is the maximum height the ball reaches above where it leaves your hand? At what times does the ball pass through half the maximum height? Ignore air resistance and take g = 9.80 m/s2. Maximum height? Earlier time at half maximum height? Later time at half maximum height?
