The 6lb slender rod AB is originally shown at rest, suspended in the vertical position. A 1lb ball is thrown at the rod with the velocity v= 50ft/s and strikes the rod at C. Determine the angular velocity of the rod just after the impact. Take e = 0.7 and d= 2ft. (See attachment for diagram)© BrainMass Inc. brainmass.com March 4, 2021, 6:07 pm ad1c9bdddf
mass of the rod M = 6 lb
mass of the ball m = 1 lb
length of the rod L = 3 ft
distance AC d = 2 ft
Initial velocity of the ball u = 50 ft/s
coeff. of restitution e = 0.7
Let us assume ...
This solution includes four steps of calculations using Newton's experimental law and the law of conservation of angular momentum.
