A student is trying to determine the muzzle velocity (initial) of a bullet that is too fast to measure directly. The student fires the 0.03kg bullet into a 6kg block of wood initially at rest. After the collision, the block, with the bullet embedded inside moves to the right with a speed of 1.29m/s right. what is the momentum before the collision of both the bullet and the block?
what is the momentum after the collision of both the bullet and the block?
how fast was the bullet fired?

What is the rate of change in a objects position?

What is the major limitation to the light microscope?

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
