a) A mildly restored ‘Knight-Rider’ 1989 Pontiac Trans Am GTA powered by a 5.7 litre V8 can do a quarter mile S from rest in a time t of about 15 seconds. Using distance: S=a t2 /2 , force: F=ma and work: W=FS, calculate the amount of work (energy) in kJ required to do the standing quarter mile given that the mass (m) of this Trans Am is 3,500 pounds. Assume that the acceleration (a) is constant. (This is not...

1. Dynamics and artificial gravity. The space station has two thrusters pointed in opposite directions. They operate by expelling propellant at high speed. The effect is that there is a force of magnitude F0 on the two ends of the space station in opposite directions, which causes the entire object to start rotating. The thrusters will stop firing when the artificial gravity created on the space station (described below) reaches the required value. Upward force, magnitude F0 Downward force, magnitude...
