On a flat field, a ball is kicked and given an initial velocity of 28 m/s at an angle of 20 degrees above the horizontal. -What are the x and y components of the ball’s initial velocity?
-From the moment it is kicked, how long will it take for the ball to reach its maximum height?
-What is the maximum height of the ball?
-Find the horizontal distance between the point at which the ball was kicked and the point where it lands.

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?
