Momentum: Calculating the Forces of a Bowling Ball

In summary: Here, the momentum changes from 16 to 0 … ?In summary, the momentum of an 8-kg bowling ball rolling at 2 m/s is 16 kg times m/s. The average force it exerts on a pillow when it stops in 0.5 seconds is 8 Newtons. The average force that the pillow exerts on the ball can be calculated using Newton's 2nd law, which states that force is equal to the rate of change of momentum.

Momentum! eww

A) what is the momentum of an 8-kg bowling bowl rolling at 2- m/s?
I got this answer which in p=16 kg times m/s

B)If the bowling bowl rolls into a pillow and stops in 0.5 sec, calculate the average force it exerts in the pillow?

C)What is the average force that the pillow exerts on the ball?

please hwlp i have no idea!

Do you know Newton's 2nd law?

F=(mv-mu)/t

Hi sweetpea1993! Welcome to PF! :smile:

Force = rate of change of momentum. :wink:

hey,
yes I know this but I'm not for sure how to put the numbers into the equation..
nice names lol :)

?? :confused:

rate of change of momentum = change of momentum divided by time. :smile:

yeah... okay so (8kg times 2m/s)- what's u stand for??
grrr i have a headache

HEY! I figured it out... you take the 16 which converts into Newtons times sec times 0.5 which gives you 8 Newtons!

(just got up :zzz: …)

No, force = change of momentum divided by time.
 

FAQ: Momentum: Calculating the Forces of a Bowling Ball

What is momentum?

Momentum is a property of moving objects that is defined as the product of its mass and velocity. In simpler terms, it is the measure of how much force an object has when it is moving.

How is momentum calculated?

Momentum is calculated by multiplying an object's mass (in kilograms) by its velocity (in meters per second). The formula for momentum is: p = m x v, where p is momentum, m is mass, and v is velocity.

What is the unit of measurement for momentum?

The unit of measurement for momentum is kilogram-meters per second (kg∙m/s). This unit is a combination of the units for mass (kg) and velocity (m/s).

How does the mass and velocity of a bowling ball affect its momentum?

The mass and velocity of a bowling ball both play a role in determining its momentum. A heavier bowling ball (higher mass) will have more momentum than a lighter bowling ball (lower mass) when traveling at the same velocity. Similarly, a bowling ball moving at a higher velocity will have more momentum than one moving at a lower velocity, regardless of its mass.

How is momentum important in bowling?

Momentum is important in bowling because it determines the force with which the ball will collide with the pins. The greater the momentum of the ball, the more force it will exert on the pins, increasing the chances of knocking them down. Additionally, understanding momentum can help bowlers adjust their technique and equipment to achieve the desired level of momentum for a successful throw.
