    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 m/s

    Initial momentum of the ball = 8x2.9 = 23.2 kg m/s

    Momentum of the ball after the impulse = 23.2 + 5 = 28.2 kg m/s

    Velocity of the ball after impulse = 28.2/8 = 3.53 m/s in the same direction

    b) For impulse b, Fdt = - 5 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 = 23.2 - 5 = 18.2 kg m/s

    Velocity of the ball after impulse = 18.2/8 = 2.28 m/s in the same direction
