A 6.00 g bullet is fired horizontally into a 1.20 kg wooden block resting on a horizontal surface. The coefficient of kinetic friction between block and surface is 0.200. The bullet remains embedded in the block, which is observed to slide 0.230 m along the surface before stopping.

Consider a plastic block with mass 0.750 kg The block is suspended from the lower end of a cord that is 1.76 m long. With the block initially at rest, it is struck by a bullet with mass 0.0132 kg and a horizontal velocity vo. After the collision, the bullet becomes embedded into the block, and the combined object swings on the end of the cord. When the block has risen a vertical height of 0.700 m, the tension in the cord is 4.80 N Part A Calculate the initial speed vo of the bullet? Express your answer with the appropriate units, HA Value |Units %3D

A 5.0 g bullet traveling horizontally with a velocity of magnitude 400 m/s is fired into a wooden block with mass 2 kg, initially at rest on a level frictionless surface. The bullet passes through the block and emerges with its speed reduced to 120 m/s. Find the speed of the wooden block just after the bullet emerges from it (m/s).

Two spheres collide on a horizontal surface (all velocities, before and after the collision, are in the x-y plane). Throughout this problem, assume that all forces aside from those exerted by the spheres themselves are negligible (at least in comparison). Sphere A has a mass of 0.65 grams.  It has an initial speed of 6.0 m/s and an initial velocity that is oriented at an angle of θ A i = 28 degrees below the x-axis. Sphere B has a mass of 0.45 grams.  It has an initial speed of 6.5 m/s and an initial velocity that is oriented at an angle of θ B i = 35 degrees above the x-axis. After the collision, sphere A has a speed of 3.5 m/s and a velocity that is directed at an angle of θ A f = 16 degrees above the x-axis. What is the final speed, in units of meters per second, of sphere B?

To test the impact resistance of a new material, a steel ball is shot through bricks of the material. Two bricks, each with a mass of 1.5 kg, are resting on a frictionless surface, a short distance apart from each other. A steel ball, with a mass of 0.118 kg, is shot into the first brick with a velocity of 174 m/s, and after passing through the first brick, it embeds itself in the second brick. The first brick has a velocity of 1.83 m/s right after the ball leaves. What is the velocity of the second brick with the embedded ball?

Shot put is a track and field event in which a heavy spherical ball (the "shot") is thrown (or "put", using the sport's terminology) as far as possible. A "shot" with mass of 6.6 kg is "put" into the air. Its initial speed is 9.6 m/s, directed at an angle 54 degrees above the horizontal. After 0.16 seconds, what is the horizontal component of the ball's velocity (in m/s)?
