1. An Astronaut standing on the moon's surface (no atmosphere) launches a small ball straight upwards with an initial velocity of +5.0 m/s. On the moon surface the acceleration due to gravity is g=1.62 m/s^2. A. Determine how high the ball travels and find numerically (3 sig. figs.) how high the ball goes. (show work as needed) (t= 6.016 sec)

B. If our astronaut doubled the speed of the upwards toss, by what factor would the high of the projectile increase? Variables can be helpful here if you know how to take ratios.

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?

Simon is writing a story about an astronaut whose spacecraft has been boarded by space pirates. the astronaut has her lucky penny in her hand behind her back as the space pirates break into the control room. she has just locked the controls so that the ship is accelerating in the direction of the control room’s ceiling. simon wants the astronaut to use the penny to hit a button on the control panel to turn off the lights and escape. the button is located a short distance behind and below the astronaut’s hands. how should simon use the theory of relativity to describe what the astronaut must do in order to hit the button?

Ahot-air balloon is 11.0 m above the ground and rising at a speed of 7.00 m/s. a ball is thrown horizontally from the balloon basket at a speed of 9.00 m/s. ignore friction and air resistance and find the speed of the ball when it strikes the ground.
