A thin rod of mass M and a length L rests on a frictionless table. this rod is stuck at a point L/4 from its center of mass by a clay ball of mass m with a speed v perpendicular to the rod. the clay ball sticks to the rod. determine the translation motion ans the rotational motion of the rod / ball combination following the collision. hint both linear momentum ans angular momentum are conserved in an inelastic collision.
An 8.66g bullet is fired into a 260g block that is initially at rest at the edge of a table of h = 1.07 m height, What is the initial horizontal velocity of the block as it flies off the table
A thin stick is placed along the x axis so that one of its ends is at x1 = 0.00 m and the other one at x2 = 1.35 m. The stick has a non-uniform mass density ?(x) = ax b, where a = 0.349 kg/m2 and b = 0.317 kg/m. What is the coordinate of the center o..
