Consider a rotating 10 kg body for which k = 0.25 m and w = 3 rad/s. What is the effect on the body's angular momentum if the mass of the body doubles?  H stays the same H doubles H quadruples H halves    A 50 kg diver is positioned so that his radius of gyration is 0.5 m as he leaves the board with an angular velocity of 5 rad/s. What is the diver's angular velocity when he assumes a tuck position, altering his radius of gyration to 0.25 m?  5 rad/s 10 rad/s 15 rad/s 20 rad/s   The knee extensors insert on the tibia at an angle of 30 degrees at a distance of 4cm from the axis of rotation at the knee. How much force must the knee extensors exert to produce an angular acceleration at the knee of 2 rad/s2, given a mass of the lower leg and foot of 5 kg and k=25cm?  31.25 N 42.45 N 21.45 N 18.25 N
