Direction, velocity and impulse of a ball.

Click For Summary
SUMMARY

The discussion focuses on calculating the impulse exerted by a ball of mass 350g traveling at 4m/s before colliding with a vertical wall and rebounding at 3m/s. The impulse can be determined using the formula for impulse, which is the change in momentum. The initial momentum is 1.4 kg·m/s (mass converted to kg), and the final momentum after rebounding is -0.105 kg·m/s, leading to a total impulse of 1.505 kg·m/s directed away from the wall.

PREREQUISITES
  • Understanding of momentum and impulse concepts
  • Familiarity with basic physics equations
  • Knowledge of vector direction in physics
  • Ability to interpret and create simple diagrams
NEXT STEPS
  • Study the impulse-momentum theorem in detail
  • Learn about vector addition and subtraction in physics
  • Explore real-world applications of impulse in sports physics
  • Practice problems involving collisions and rebounds
USEFUL FOR

Students studying physics, particularly those focusing on mechanics, as well as educators looking for examples of impulse and momentum in action.

Homework Statement



A ball of mass 350g is traveling with a speed of 4m/s when it hits at right angles a fixed vertical wall. The ball rebounds with a speed of 3m/s. Find the magnitude of the impulse exerted by the ball on the wall. Using a simple diagram show the direction of velocities and the impulse.

Hi all i can't seem to finish my coursework, I'm stuck into questions that, i can't solve.

can some one help me please?
