- Consider a wood block of mass 1.00 kg, tied to a massless string of length 2.00 m, that is shot with a bullet of mass 5.00 g and a speed v = 400 m/s. The bullet goes through the block and continues out the other side, but with a smaller velocity.Treat the block as a point-like mass. i. What is the angular momentum of the bullet about the point where the string is tied? ii. If the block eventually rises to a height 0.45 m above its initial height, what is its velocity just after the collision? What is its angular mometum? iii. What is the angular momentum of the bullet immediately after the collision, since angular momentum is conserved? What is the velocity of the bullet after the collision?A 3 kg plank is 0.6 m in length and has its center of mass at the geometrical center.

- Determine the magnitude of the moment about the line "og" of a force of 11 N in the defined direction from point "f" to "b". Where x = 2.2 m, y = 2.5 m, z = 5.7 mA piece of putty of mass m = 0.75 kg and velocity v = 2.5 m/s moves on a horizontal frictionless surface. It collides with and sticks to a rod of mass M = 2 kg and length L = 0.9 m which pivots about a fixed vertical axis at the opposite end of the rod as shown. What fration of the initial kinetic energy of the putty is lost in this collision? KEJost/KEinitialA solid sphere of mass, M = 5.0 kg, and radius, R = 0.100 m is placed on two blocks so that it’s centre of mass lies at the origin as shown on the right. A bullet of mass, m = 0.100 kg, and with an x coordinate of b = 0.04 m strikes the sphere from below with a vertical velocity, v = 65 m/s and embeds in the sphere coming to rest at the location (-b,0) in the diagram below. Since there is no momentum in the horizontal direction, after the bullet hits the sphere , it will rise up to some maximum height and then fall back to its initial position on the two blocks. While the sphere is in the air it will rotate. What is the magnitude of the angle (in degrees) through which the sphere will rotate before it makes contact with the two blocks again?

It is capable of spinning around a frictionless axle that goes through the top of the rod. A 2.5 kg mass of clay collides perfectly idealistically with the bottom of the rod. The clay was traveling perfectly horizontally with a speed of 12 m/s before the collision. How fast will the rod with the clay attached to it rotate around the axle in radians per second? The only external force on the clay/rod system come from the axle, which exerts no torque about itself.
