1. Two masses m and m2 are situated in a system with ideal pulleys as shown in the figure. This system is in the vertical plane. A spring (constant k, rest length ) connects mass m with the ground. Data: m= 1.5 kg, m = 2 kg, m3= 1.5 kg, k = 50 N/m, l = 0.4 m, h= 2 m. a) The system is in rest at t = 0 s. Determine at that instance the tension in all the ropes and the compression/extension of the spring. b) Then, an extra mass m3 is dropped from a height h, hits mass m and sticks to that mass. During this very short impact, the spring does not exert an impulse. Determine the velocities of all the masses in the system right after the impact and also the impulses exerted by the ropes.
