3. Mass m is in rest on an inclination. Mass m is released from rest at a distance d (measured along the inclination) from m. There is no friction along the inclination, over the distance d. Mass m2 hits mass mi in such a way that the two masses stick together. During this very short collision, mass m does not get an impulse from the cable. Immediately after the collision, the system moves with the cables taut and with the two masses moving down the inclined plane with a speed of 0.3 m/s, and with the spring stretched over 0,15 m (= elongation). On that part of the inclination, there is friction between the inclination and the masses (k = 0.15). Data: k = 200 N/m, mass m = 6 kg, mass m2 = 4 kg. Remark: the cable passes through a hole in mass m2 so that there is no contact between the cable and mass m2. Determine: a) the distance di b) the distance d2 which is the distance that the two masses travel (after the collision) along the inclined plane before they come to rest. 50 2 mi WWW d m2 d 2
