Mary and Jane are standing at each end of an ice board 1.0 m in length. 2 points The ice board rests on frictionless ice. Mary throws a 5.0 kg ball
horizontally to Jane who catches it. Given that the mass of Mary, Jane and
the ice board are 42 kg, 40 kg and 3.0 kg respectively, what is the distance
travelled by the ice board before coming to rest again? *
0.053 m
0.056 m
0.059 m

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?
