Inelastic collision and velocity of car

Click For Summary
SUMMARY

The discussion centers on calculating the final velocity of a 2000 kg car traveling west at 75 km/h and a 1000 kg motorcycle traveling south at 108 km/h after a completely inelastic collision. Momentum conservation principles are applied, where the total momentum before the collision equals the total momentum after. The solution involves calculating momentum in both the east/west and north/south directions, using the formula for momentum (mv) for each vehicle before and after the collision.

PREREQUISITES
  • Understanding of momentum conservation principles
  • Knowledge of vector addition for velocities
  • Familiarity with inelastic collisions
  • Basic algebra for solving equations
NEXT STEPS
  • Study momentum conservation in two dimensions
  • Learn how to calculate final velocities in inelastic collisions
  • Explore vector addition of velocities
  • Review examples of inelastic collision problems
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and collision theory, as well as educators seeking to explain inelastic collisions and momentum conservation.

Homework Statement



2000 kg car traveling west at 75 km/h and a motorcycle traveling south at 108 km/h weighing 1000kg. assuming the collision is completely inelastic, what is the velocity of the vehicles after the collision.

Homework Equations



I know that the Pi, system = Pf, system.

The Attempt at a Solution


I am just confused of where to start. Any pointers into the correct direction would be greatly appreciated.

"Completely inelastic" means they stick together.
Momentum is conserved in both the north/south direction and the east/west direction. You must write
momentum before = momentum after
for both directions, put in an mv for each moving object before and after.
Put in the known numbers and you will be able to work out the velocity after the collision in each direction.
