(non calculus physics)
A college fullback weighing 100 kg is running north at a speed of 4.5 m/s when he is tackled by a 110 kg linebacker running east at 3.5 m/s. Assume the collision is perfectly inelastic.
- Find the velocity of the players just after the tackle.
- Find the kinetic energy lost as a result of the collision.
- How do you account for this apparently “lost” energy?

please help with the breakdown of units
Constants A 86-kg fullback is running at 3.6 m/s to the east and is stopped in 0.85 s by a head-on tackle by a tackler running due west. Calculate the original momentum of the fullback Express yodiSanswer to two significant figures and include the appropriate units. Enter positive value if the direction of the momentum is to the east, and negative value if the direction of the momentum is to the west.
