Question

a 0.15kg baseball travel at a rate of 35m/s and collide and stick to a catcher milt and hand. the milt and hand are intally at rest and have a mass of 10kg. what is the final volcity of the mitt,hand,and ball?

Answer 1

4.57 m/s

Step-by-step explanation:

mass of baseball (m1) = 0.15kg

velocity of baseball (v1) = 35 m/s

mass of milt and hand (m2) = 10kg

velocity of mitt and hand (v2) = 0 m/s

final velocity of mitt, hand, and ball = vf

Conservation of momentum since they are colliding and sticking together after collision:

Pb = Pa

m1v1 + m2v2 = (m1+m2)vf

plug in:

(0.15kg)(35m/s) + (10kg)(0m/s) = (0.15kg + 10kg)vf

5.25 = 1.15vf

vf = 4.57 m/s
