Kindly answer number 7 with complete solution #5. In ice hockey, a puck of mass 5.0 kg moving at 2.0 m/s approaches an identical puck that isstationary on frictionless ice. After the collision, the first puck leaves with a speed v, at 30" to theoriginal line of motion; the second puck leaves with speed v, at 60", as in Figure 2.(A) Calculate the speeds v, and v.(B) Was the collision elastic? Justify your answer by showing the kinetic energies.#6. A 1.0 kg steel ball and a 2.0 m cord of negligible mass make u simple pendulum that can pivotwithout friction about the point O, as in Figure 3. This pendulum is released from rest in a horizontalposition, and when the ball is at its lowest point it strikes a 1.0 kg block sitting at rest on a shelf.Assume that the collision is perfectly elastic and that the coefficient of kinetic friction between the blockand shelf is 0.10.(A) What is the velocity of the block just after impact?(B) How far foes the bock slide before coming to rest (assuming that the shelf is long enough)?20m#7. Four objects are situated along the y axis as follows: a 2.00 kg object is at 3.00 m, a 3.00 kgabject is at 2.5 m, a 2.50 kg object is at the origin, and a 4.00 kg object is at -0.500 m. Where is thecenter of mass of these objects?

Given data: m1 = 2.00 kg at y1 = 3.00 m m2 = 3.00 kg at y2 = 2.5 m m3 = 2.50 kg at y3 = 0 m m4 =…
