Arod of length l and mass m sits on a frictionless tabletop. a very small piece of putty of mass m slides perpendicular to the rod at a speed of vo and sticks to the end of the rod. a. draw a diagram showing the motion of the rod and putty after the putty hits the end of the rod. b. determine the speed of the rod and putty's translational motion. c. determine the speed of the rod and putty's rotational motion.

Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative
