Question

A 150 kg inside linebacker moving west at 1.6 m/s tackles a 90 kg football quarterback moving east at 8 m/s. After the collision, both players move east at 2 m/s. Draw vector diagramsin which the before and after collision momenta of each player arerepresented by a momentum vector. Label the magnitude of each momentum vector. Also, determine the type ofthe occurring collision.

Answer 1

the players stay together the kid is inelastic

Step-by-step explanation:

The magnitude of the vectors is given by the product

p = m v

Stop in linebacker

p₁ = m₁ v₁

p₁ = 150 1.6

p₁ = 240 kg m / s

Vector on the left

For the quarterback

p₂ = m₂ v₂

p₂ = 90 8

p₂ = 720 kg m / s

Vector to the right

To the final point with the players together

p₃ = (m₁ + m₂) v

p₃ = (150 + 90) 2

p₃ = 480 kg m / s

Vector to the right

All on the x axis. see attached.
