Tossing Rocks on Frictionless Ice: Calculating Angle and Speed

Click For Summary
SUMMARY

The discussion focuses on a physics problem involving a person with a mass of 65.0 kg tossing a 4.5 kg rock at an initial speed of 12.0 m/s on frictionless ice. The rock lands 15.2 m away, prompting calculations for the angle of toss and the speed of the person after the toss. The solution requires applying the principles of conservation of momentum and projectile motion to derive the angle and the resulting speed of the person.

PREREQUISITES
  • Understanding of conservation of momentum
  • Knowledge of projectile motion equations
  • Familiarity with basic physics concepts such as mass and velocity
  • Ability to perform vector decomposition
NEXT STEPS
  • Study conservation of momentum in two-dimensional collisions
  • Learn about projectile motion and its equations
  • Explore vector decomposition techniques in physics
  • Practice solving similar physics problems involving motion on frictionless surfaces
USEFUL FOR

Students studying physics, educators teaching mechanics, and anyone interested in solving real-world physics problems involving motion and forces.

While standing on frctionless ice, you (mass 65.0 kg) toss a 4.5 kg rock with initial speed 12.0 m/s. IF the rock is 15.2 m from you when it lands, (a) at what angle did you toss it? (b) How fast are you moving?

I'm still having trouble with these.
