A 2.0-kg block of wood is on a level surface where μs and μk = 0.60. A 13.7-N force is being applied to the block parallel to the surface.
a. If the block was originally at rest, then
1. it will remain at rest, and the force of friction will be about 15.7 N.
2. it will remain at rest, and the force of friction will be about 13.7 N.
3. it will remain at rest, and the force of friction will be 11.8 N.
4. it will begin to slide with a net force of about 1.9 acting on the block.
b. If the block was originally in motion, and the 13.7-N applied force is in the direction of motion, then
1. it will accelerate under a net force of about 1.9 N.
2. it will move at constant speed.
3. it will decelerate under a net force of about 1.9 N.
4. it will decelerate under a net force of 11.8 N.

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?
