skg O - Ol kg 8m/s 2. (40 pts. ) A disk of mass m slides along a sheet of ice with a speed vo before exploding into two pieces of mass m) and m2. The mass m2 continues moving in the same direction with a speed v2 before making a perfectly inelastic collision with a block of mass me that hangs from a string of length I and negligible mass. Assume that the hanging mass has the same vertical coordinate as mass m2 during the collision. i kg Let m = 5.0000 kg, m2 = 1.0000 kg, vo = 4.0000 m/s, v2 = 8.0000 m/s, m3 = 1.5000 kg, and L = 85.0000 cm. (a) What is the speed of my after the explosion? Does it continue to move in the same direction after the disk explodes? (b) What is the impulse delivered to my by m2 during their collision? (c) When the m2/m3 system has an angular acceleration of 7.4110 rad/s2, find the angle of 0 that the string makes with the vertical, and the tension in the string. (d) How would the expression for the mechanical energy of the system change if the hanging mass m3 was described as a sphere of radius r,? Your answer should include any new information that describes m3
