mass of bullet m = 12.0 gm = 12*10^(-3) kg
speed of bullet u = 380 m/s
mass of pendulum M = 6.0 kg
length of the cord l = 70.0 m

Intial K.E. of bullet = (1/2)*m*u^2 ...

  • 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

  • Elastic and Inelastic Collisions

    That is, velocity of bullet = 90 times the velocity of the bullet+block after collision Now to the second part..

  • Conservation of Energy and of Momentum

    Find v, the velocity of the bullet before impact. During the collision, momentum must be conserved, so: 'momentum of bullet before collision equals the momentum of block and bullet after collision'.

  • Speed of a bullet measured using ballistic pendulum !

    The momentum of the bullet (m1v1) before the collision with the block has to equal the momentum of the block-bullet system after the collision. The collision between the block and the bullet is inelastic, so kinetic energy (KE) is not conserved.

  • collision between a bullet and a wooden block of a pendulum

    102501 collision between a bullet and a wooden block of a pendulum A 2.50 g bullet, traveling at a speed of 425 m/s, strikes the wooden block of a ballistic pendulum. The block has a mass of 215 g.

  • Bullet Motion and Conservation of Energy

    The initial momentum of the bullet of mass Mb (just before the collision) is: The momentum after the collision with a block of mass MB is: Therefore: We recall that we already found vf which is the velocity of the block-bullet system after the

  • Conservation of Momentum in One Dimensional Collisions

    If the block rises through a distance h=12.1cm, what was the velocity of the bullet as it emerged from the block? Inelastic collision - bullet gets embedded into the pendulum block after collision and the combined mass moves as one.

  • Mechanics: 3 Probles on conservation of energy and momentum

    Part C What is the speed of the block/bullet system after the collision?

  • Block-Bullet System

    (a) Before the collision, only the bullet carries a velocity, so the initial momentum will be: pi = 0.0081 kg * 850 m/s = 6.885 kg m/s Let us say that the velocity of the block/bullet system immediately after the collision is v'.
