A 1.5 kg block of clay is tied to the end of a string. A 327 g steel ball impacts the clay from the left, embeds itself into the clay, and causes both to rise a height of 23 cm. Find the entrance velocity of the ball. (Hint: this is an inelastic collision!)

A steel ball of m = 0.80 kg is attached to a string of 1.5 m length directly above the edge of a block (m = 5.0 kg) which can slide frictionless on a plane. The ball gets deflected by 45° , is then released and hits the block elastically and centrally. Calculate the maximum deflection angle of the ball after the collision.

A clay ball (m=0.82 kg) is thrown at a metal target (M=1.72 kg) that is suspended from a cable. The ball is released 1.5 m above the ground at an angle of 32 degrees. There is a completely inelastic collision between the ball and the target of height of 7.1 m. At collision, the ball is moving horizontally. How far above its hanging location does the target swing?

5. A ball is attached to one end of a wire, 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 inelastic. The masses of the ball and block are, respectively, 1.5 kg and 2.4 kg, and the length of the wire is 1.21...

The ballistic pendulum is a simple device—the pendulum part consists of a wooden block, which has a mass of 860. grams, hanging from a string. The block is initially at rest. However, a bullet with a mass of 18.0 grams is fired at the block. The bullet embeds itself in the block, and the bullet and block then oscillate back and forth on the string, pendulum style, after the collision. Just before impact with the block, the bullet's velocity is...

A steel ball of mass 0.470 kg is fastened to a cord that is 92.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal, as shown in the figure. At the bottom of its path, the ball strikes a 2.90 kg steel block initially at rest on a frictionless surface. The collision is elastic. Find (a) the speed of the ball and (b) the speed of the block, both just after...

6 points) A Wooden block of mass M-1 ke is hanging from a string 50 cm long. A 3 gram bullet is tired at block of wood as shown below (left drawing). The bullet embeds itself in the wood, and the block swings up on the right to a maximum height such that the pendulum string makes an angle of 30° with respect to the vertical. How fast was the bullet going before it hit the wooden block? L-50 cm...

In the figure, block 2 of mass 2.60 kg oscillates on the end of a spring in SHM with a period of 24.00 ms. The position of the block is given by x = (1.60 cm) cos(wt + pi/2). Block 1 of mass 5.20 kg slides toward block 2 with a velocity of magnitude 7.20 m/s, directed along the spring's length. The two blocks undergo a completely inelastic collision at time t = 6.00 ms.
