A 8.0 kg bowling ball is rolling down the alley with a velocity of 2.9 m/s. For each impulse, a and b, as shown in Figure 9-3, find the resulting speed and direction of motion of the bowling ball.
_________m/s in the same direction or in the opposite direction?
_________ m/s in the same direction or in the opposite direction?
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 ...
Speed and motion of bowling balls for each impulse is determined.
