A pitcher throws a slow ball straight across the plate at 40.0 m/s. The batter hits the 0.200 kg ball straight back at 60.0 m/s. If the bat is in contact with the ball for 0.500s,

a) What is the initial momentum of the ball?

b) What is the final momentum of the ball?

c) What is the change in momentum of the ball?

d) Use the impulse-momentum theorem to find the force experienced by the ball.

Please explain the equations and show the work as I have no idea what I am doing. Please state what each letter in the equation stands for.

Solution Summary

Momentum (and velocity) is a vector quantity so we have to define ourselves a positive direction (to batter) and a negative direction (to pitcher).

Solution Preview

Momentum is represented by p and is the product of mass and velocity.

p = mv

  • Jumping Off a Raft

    This is a problem related to momentum and its conservation. Momentum(p)= Mass * Velocity and in a closed system it is conserved i.e. Initial momentum=Final momentum.

  • Conservation Laws- Inelastic collison

    Whether total momentum is more than the initial momentum is analysed.

  • Impulse and Velocity

    Momentum = mass * velocity Impulse = force * time = change in momentum = mass * (Vfinal - Vinitial) Initial momentum of the car + rider system is, = Momentum of cart + momentum of boy = 50 * 2 + 70 * 2 = 240 Kg m/s Initial momentum = final momentum

  • Impulse Momentum, Conservation of Linear Momentum, & Collisions

    Initial momentum of ball 1 = 5 x 2 = 10 kg.m/s Initial momentum of ball 2 = 0 Final momentum of ball 1 = 5v1 Final momentum of ball 2 = 7.5v2 By conservation of momentum: Net momentum after collision = Net momentum before collision:

  • Collision



    The total momentum just before the impact:
    Momentum of the 2 kg mass is 2 kg * 20 m/s = 40 kg m/s.
    Momentum of the 3 kg mass is 0 (at rest).
    Total momentum = 40 kg m/s.

  • Physics: Momentum and Speed

    Momentum of the block + bullet after collision = (8.35+0.005)v As per the law of conservation of linear momentum: Net momentum of the block and bullet before collision = Net momentum after collision Hence, (8.35+0.005)v = 0.548 v = 0.548/8.355
