t was Hannah's birthday and she had a pinata filled with candies in it. The pinata's mass is 3.4 kg. Feliz swung a 0.8 kg bat at 4.4 m/s to try breaking the pinata. The attempt was unsuccessful and the pinata only cracked and moved in swining motion. Find the swinging speed of the pinata after being hit by the bat.

A 33.7-g rifle bullet traveling 205. m/s buries itself in a 2.97-kg pendulum hanging on a 2.67-m-long string, which makes the pendulum swing upward in an arc. Determine how high (in m) the pendulum swings above its original position.

A small ball of mass mb = 0.050 kg is projected into a pendulum of mass Mp = 0.200 kg in a ballistic pendulum experiment. How fast does the ball need to go in order to get the pendulum to swing up to a height of h = 0.25 m above its original position?     2.21 m/s     0.111 m/s     11.1 m/s     0.553 m/s

A 1.5-kg block is attached to the end of a 1.9-m string to form a pendulum. The pendulum is released from rest when the string is horizontal. At the lowest point of its swing when it is moving horizontally, the block is hit by a 0.02-kg bullet moving horizontally in the opposite direction. The bullet remains in the block and causes the block to come to rest at the low point of its swing. What was the magnitude of the bullet's velocity just before hitting the block?

. What is the initial kinetic energy in joules of the bullet in problem 1? What is the final kinetic energy of the combined bullet/pendulum?

1. An inventor patents a "golf machine". It consists of a "golf club" which is really a pendulum of length L = 2 (m), with a massles string and a mass M = 30 (kg) on the end. By pulling back on the pendulum until the string makes an angle 0= 10° from the vertical, and then releasing it from rest, the golf club strikes the "golf ball" exactly horizontally. The golf ball is a mass m = 0.1 (kg) that rests on a platform which is h = 20 (cm) above the horizontal ground. Assume that all collisions are elastic and all masses are point masses. Finally you should ignore air resistance but gravity acts down as usual. L %3D M) m h How far does m travel horizontally (before it hits the ground)? |How long does it take from the time M is released from rest to the time it strikes m? [Hint: think pendulum]

A ball is attached to one end of a vwire, the other end being fastened to the ceiling. The wire is held horizontal, and the ball is released from rest (see the drawing). It swings downward and strikes a block initially at rest on a horizontal frictionless surface. Air resistance is negligible, and the collision is elastic. The masses of the ball and block are, respectively, 1.7 kg and 2.5 kg, and the length of the wire is 1.23 m. Find the velocity (magnitude and direction) of the ball (a) just before the collision, and (b) just after the collision. (a) v = i (b) v = i > >

A 15 gram bullet is fired horizontally into a 0.836 kg wooden block suspended from the ceiling.  The bullet is embedded in the block.  The block, with bullet inside, swings upward and rises a vertical distance of 0.38 m.  What is the initial speed of the bullet before striking the block?
