• Speed and motion of bowling ball for each impulse

  a) By definition, Impulse Fdt = d(mv) [change in momentum] For impulse a, Fdt = 5 Ns (or kg m/s) Change in momentum of the bowling ball = +5 kg m/s Initial momentum of the ball = 8x2.9 = 23.2 kg m/s Momentum of the ball after the impulse

• Working with Momentum and Impulse

  
  
  Impulse = 11.88 kg m/s (opposite to the initial momentum, put a -ve sign)
  
  Final momentum = Initial + change = 5.94 + (-11.88) = -5.94
  
  (-ve sign only says that the motion is in the opposite direction)
  
  Thus, mass

• Impulse concepts

  Force, by Newton's second law, is the time rate of change of momentum. If the climber falls, his momentum falls to zero quickly. That is if a short time period is required to stop, then the impulse force will be high.
