![4.
An 85 kg running back moving at 7.0 m/s makes a perfectly inelastic collision with a 105
kg linebacker who is initially at rest. What is the speed of the players just after their collision?
Conservation of momentum: Using
Pi = Pf
inclastic collision
→ m, V, + m,V, =: (m,+ m,) V¢
* 85(1) + 1os(o) + (e5 +1o5) Vf
→ Vg = 3.13 mls](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb234898a-ca00-4740-ae3d-79576f672843%2Fdd36e753-f40b-4884-8917-bbe5b4f9bf24%2Fhvhjs3_processed.jpeg&w=3840&q=75)
