Problem 1 The three spherical objects in Fig. 1 have each mass 2.75 kg are connected by mass-less hinged rigid links of equal length. The system is released from rest in the position shown and it slides down the quarter circular slide in the vertical plane. When the upper sphere reaches the bottom position, the three spheres have speed 1.56 m s-1 1. Calculate the energy loss due to friction from the release state to the bottom one 2. Calculate the total impulse on the system of three spheres during the same interval 360 mm Fig. 1: Problem 1
