A pendulum bob of mass m starting at a height of 0.2 m, which is also the string length L) collides with a block of mass 3m at the bottom of its swing.The block proceeds to move d=20 cm along a surface with a coefficient of friction equal to 0.25 before coming to rest.What happens to the pendulum bob after the collision (i.e. how high does it go and in what direction)? Is the collision elastic or inelastic?

A 1.2 kg glider moving at 3.0 m/s [right] undergoes an elastic head-on collision with a glider of equal mass moving at 3.0 m/s [left]. The collision is cushioned by a spring whose spring constant, k, is 6.0 x 104 N/m. Determine the compression in the spring when the second glider is moving left at 1.6 m/s.

A 11 g bullet is fired into the bob of a ballistic pendulum of mass 1.3 kg. When the bob is at its maximum height, the strings make an angle of 60° with the vertical. The length of the pendulum is 2.3 m. Find the speed of the bullet. m/s еВook

A billiard ball moving at 5.20 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 4.67 m/s at an angle of 26.0° with respect to the original line of motion. Assuming an elastic collision (and ignoring friction and rotational motion), find the struck ball's velocity after the collision. magnitude direction 1.56 × Check the initial and final kinetic energies. You will find that your final kinetic energy is not equal to the initial kinetic energy. m/s ° (with respect to the original line of motion)

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 > >

In the figure, block 1 of mass m1 slides from rest along a frictionless ramp from height h and then collides with stationary block 2, which has mass m2 = 3m1. After the collision, block 2 slides into a region where the coefficient of kinetic friction is μk and comes to a stop in distance d within that region. What is the value of distance d if the collision is (a) elastic and (b) completely inelastic? Express your answer in terms of the variables given and g.

In a ballistic pendulum experiment, a small marble is fired into a cup attached to the end of a pendulum. If the mass of the marble is 0.0235 kg and the mass of the pendulum is 0.250 kg, how high ℎ will the pendulum swing if the marble has an initial speed of 5.95 m/s? Assume that the mass of the pendulum is concentrated at its end so that linear momentum is conserved during this collision.
