A uniform thin rod of length 0.50 m and mass 3.5 kg can rotate in a horizontal plane about a vertical axis through its center. The rod is at rest when a 3.0 g bullet traveling in the rotation plane is fired into one end of the rod. As viewed from above, the bullet's path makes angle = 60° with the rod If the bullet lodges in the rod and the angular velocity of the rod is 14 rad/s immediately after the collision, what is the bullet's speed just before impact?
m/s

A particle moves along a straight line with velocity v⁡(t)=t+2 meters/second. Assume that the time t is measured in seconds. Suppose that t[0] .. t[3] divide the interval [2, 8] into 3 equal intervals. Use these subintervals and the right endpoints as sample points to compute a Riemann sum which approximates the distance traveled by the particle for the interval of time [2, 8].
