Physics

Draw free body diagrams for the motorcycle rider for each of thefollowing situations. Label all your force vectors clearly, anddraw them in a self-consistent manner – that is, forces that cancel(sum to zero) should be drawn so that they cancel on your diagram.In all diagrams, assume the motion is towards the right. Amotorcycle rider falls off her Harley while attempting to pop awheelie.

  1. The motorcycle rider skids along the surface of a horizontalroad, slowing down slightly in the process.
  2. The road dips, so the sliding motorcycle rider picks up speedas she skids along the asphalt.

The rider eventually slides to a stop.An ambulance arrives and two burly EMTs place the rider on agurney

  1. The EMTs hoist the gurney straight upwards to get it level withthe bed of the ambulance.
  2. With the motorcycle rider inside, the ambulance acceleratesalong the horizontal road towards the hospital.
  3. The ambulance drives towards the hospital along a straight,horizontal road at a steady 40 mph.

B. The rider is put in traction at the hospital. A force of 120N at an angle of 29º from the vertical is applied to her femur. Howmuch force should be applied to her tibia (at 70º from thevertical), so that the resultant net traction pull is directed at23º from the vertical?
