Problem 3: Two smooth billiard balls A and B each have a mass of 500 g. If A strikes B with a velocity (VA)1 - 1.5 m/s as shown, determine their final velocities just after collision. Ball B is originally at rest and the coefficient of restitution is e0.75. Neglect the size of each ball. Use conservation of linear momentum in x-direction, equation of restitution and conservation of momentum...

A metal block of mass M = 1.99 kg rating on a horizontally as shown below is hit by a bullet of mass m = 1.00 times 10^2 kg shot vertically from underneath. At the moment of impact the bullet was moving upward with a speed v = 350 m/s. After the impact, the block jumps to height of 0.625 m above the surface. a) Find the velocity of the block acquired during the impact. b) Find velocity of the...
