A baseball has a mass of 0.15 kg. A pitcher throws a 40 m/sec fastball which is caught by the catcher. What is the change in momentum of the ball?
What is M*changeinvelocity?
so .15 x 40? because the initial velociy equals zero?
yes. include units.
The next part of the questions says What is the impulse on the catcher’s mitt?
to find impulse do I use the equation
with vf = 0m/s and vi= 40m/s
