SUMMARY

The discussion focuses on a perfectly inelastic collision between a 89.3 kg fullback and a 94.7 kg opponent, where the fullback runs east at 4.91 m/s and the opponent runs north at 2.98 m/s. The post-collision speed and direction of the combined mass are calculated using momentum conservation principles. Additionally, the energy lost during the collision is determined, highlighting the importance of accounting for energy dissipation in inelastic collisions.

PREREQUISITES
  • Understanding of momentum conservation principles
  • Knowledge of inelastic collisions
  • Familiarity with vector addition in physics
  • Basic calculations involving kinetic energy
NEXT STEPS
  • Study the principles of momentum conservation in two-dimensional collisions
  • Learn how to calculate kinetic energy before and after collisions
  • Explore the concept of energy loss in inelastic collisions
  • Investigate real-world applications of collision physics in sports
USEFUL FOR

Physics students, sports scientists, and anyone interested in the mechanics of collisions in sports contexts.

A 89.3 kg fullback running east with a speed of 4.91 m/s is tackled by a 94.7 kg opponent running north with a speed of 2.98 m/s.

(a) If the collision is perfectly inelastic, calculate the speed and direction of the players just after the tackle.
___m/s___° (north of east)
(b) Determine the energy lost as a result of the collision.

___J
Account for the missing energy.
