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 P=mV = 0.15Kg x 26M/s = 3.9Kgm/s. Then what equation?
I = F deltaT = m deltaV
deltaT=m deltaV / F = 3.9/390 = .01s Is that correct?
What about last question of travel distance. Is speed constant?
