Question
While playing a game of pool over at the HUB,you attempt to make a bank-shot with the cue ball. (A bank shot is one in which you intentionally direct the ball at the side bumpers so as to deflect it, typically because you do not have a direct shot.) The ball's momentum vectors before and after colliding with the side bumper are shown below.
If the ball was in contact with the bumper for 0.010 seconds, what was the average magnitude of the force that the bumper exerted on the ball?
bank shot is one in which you intentionaly direct the ba ball (A deflect it, typically because you do not have a direct shot.) The and after colliding with the side bumper are shown below. P -(3 kg. m/s)x+(3 kg. m/s)) . = (3 kg. m/s)x+(-3 kg·m/s)) If the ball was in contact with the bumper for 0.010 seconds, w son thot the huer exerted on the bal?Explanation / Answer
here,
P1 = (3i + 3j) kg.ms
P2 = (3i -3j) kg/ms
del(P) = 3i -3j - 3i - 3j
Del(p) = -6j
as we know
Impulse = Change in momentum
Favg*Time = del(p)
Favg = -6j/0.010 = -600j
Fnet = Sqrt(fx^2 + Fy^2)
Fnet = 600 N
