PROBLEM 1: A 12-lb rod ABC is impacted by a 2-lb object DE as shown. The object embeds into the end of the rod at point C, determine immediately after the impact (a) the angular velocity of the rod ABC, (b) the angular acceleration of the rod ABC, A 2 B Unit: ft (c) the components of the reaction at B. 12 Assume that the object and the rod move as a single body after the impact. Vo = 35 ft/s C E D 6

Please answer both questions clearly thanks

PROBLEM 2: A baseball catcher includes a 6-kg rod with a small net of negligible mass at point B. A spring of unstretched length 0.3 m is attached to the midpoint of bar AB at one end and to stationary point D at the other. A stopper at point E keeps the catcher in the vertical position before the pitch. Knowing the catcher just barely rotates when it catches a fastball of mass 0.18 kg, determine the required spring constant of the spring. Given = 1.5 m. Bonus: Develop a MATLAB program to solve for this problem. v₁ = 40 m/s Unit: m 1 B L E A D www wwwwwww -L-
