  • Angular Velocity of a Block on a Heated Spinning Rod

    Initially, a small piece of wax holds the block 10.0 cm from the pivot. The block is spun at 50.0 rpm, then the temperature of the rod is slowly increased. When the wax melts, the block slides out to the end of the rod.

  • Conservation of Energy and of Momentum

    The block with embedded bullet then rises a total distance H= 1.2 meters above its initial position. Find v, the velocity of the bullet before impact.

  • Conservation of Linear Momentum and Impulse

    (b) Determine the change in momentum of the projectile? (c) What was the muzzle velocity of the projectile? 3)A fireworks rocket rises straight up to its maximum altitude of 50.0 m.

  • Heat, harmonics, power, calories, efficiency, velocity, wave

    Hence, 1960 J heat raises the temperature of the block. Q = mct where m = mass, c = specific heat, t = temperature rise 1960 = 2 x 670 x t t = 1.46OC Final temperature of the block = 21.46OC 9.

  • Speed of a bullet measured using ballistic pendulum !



    From the law of conservation of momentum, we can write

    mv = (M+m)V ........>(2)

    (Note that v is the velocity of the bullet and V is the velocity of the bullet+block system, M+m is the mass of the bullet

  • 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.

  • Elastic collision

    Initial velocity of ball = 5 m/s Initial velocity of block = 0 Let the velocity of the ball immediately after collision be V1 and that of the block be V2.

  • Classic heat transfer/heat capacity problem
