W = KE-f - KE-0 W = 1/2 m(V-f)2 - 1/2m(V-0)2 W = 0 - 1/2 * .15 * (26)2 = 50.7 D = -50.7/F = 50.7/350 ?

Thanks for the help!

work = force x distance moved. There are two variables I do not know in this equation...

somewhat, where do you suggest I look specifically?

Homework Statement A 0.15 kg baseball moving at +26 m/s is slowed to a stop by a catcher who exerts a constant force of 390 N. How long does it take this force to stop the ball? How far does the ball travel before stopping? Homework Equations The Attempt at a Solution For...

A 0.15 kg baseball moving at +26 m/s is slowed to a stop by a catcher who exerts a constant force of 390 N. How long does it take this force to stop the ball? How far does the ball travel before stopping? P=mV = 0.15Kg x 26M/s = 3.9Kgm/s. Then what equation?

So I have one more problem to solve. Can you help? A 0.15 kg baseball moving at +26 m/s is slowed to a stop by a catcher who exerts a constant force of 390 N. How long does it take this force to stop the ball? How far does the ball travel before stopping? - P=mV = 0.15Kg x 26M/s =...

Thank you for the help!

you need less force to stop the object

impulse is a factor of both force and time. So the egg hitting the pillows (let's say) is the impulse and for a period of time to slow the egg down?

Well I know we would need to slow down the object gradually to keep intact, such as using a stack of feathers or pillows. How does the theorum apply?

I have a question I am looking for an asnwer: Using the impulse momentum theorum, describe how it is possible to drop an egg from a 2 story high building and not have the egg break.
