6. a 7-kg bowling ball moving at 6.0 m/s strikes a 1-kg bowling pin. 11 we van
slows to 4.5 m/s in 0.05 s, how much force does it exert on the pin?
chanter 7. momentum

210 N

Explanation:

The change in momentum of the ball is equal (in magnitude) to the impulse given to the pin, according to

(1)

where

is the change in momentum of the ball

F is the force exerted on the pin

is the duration of the collision

For the bowling ball, we have

m = 7 kg (mass)

u = 6.0 m/s (initial velocity)

v = 4.5 m/s (final velocity)

So, the change in momentum (in magnitude) is

We also know the duration of the collision,

And so if we re-arrange eq.(1), we find the force exerted on the pin:

b mirrors submit a iisner? e. for which optical devices does d sometimes have a positive value? o a a and b o b. a and c o c. b and d 0 d. b and cb

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
