System of interestBeforeLeads to a PerfectlyInelastic CollisionmFrictionless ice surfaceAs shown above, a 0.140-kg ice hockey puck (m1) has a velocity of 35.0 m/s and is moving to the right (in the positive x direction) toward a 60.0-kg ice hockey goalie (m2)who is originally moving backward (.e., toward the right, in the positive x direction) at 0.100 m/s. The puck and goalie have a perfectly inelastic collision. We can assumethat the friction between the ice and the puck-goalie system is negligible as is the air resistance.Although I will not be collecting the details of your work on this problem because it is an online multiple-choice question, I urge you to follow the steps outlined below tosolve it.(a) Use the GFS method to show and explain each step of your work.(b) Draw a sketch of the puck-goalie system before and after the collision, being sure to label and draw correctly all the velocities involved. Use m1, m2, v1, v2, and v' tolabel the before-and-after sketch.(c) Immediately after this perfectly inelastic collision, what is the recoil velocity of the puck and goalie in m/s to three significant figures? To answer this question, write outthe equation you will use to find the reccil velocity, simplify it using the Given, and then solve for the recoil velocity v' in m/s to three significant figures.(d) To check your work, calculate the change in the puck-goalie system's intemal kinetic energy (AKE). To find AKE, calculate to three significant figures the total internalkinetic energy of the puck-goalie system just prior to the collision (KE) and then subtract it from its total internal kinetic energy to three significant figures just after thecollision (KE'). For this problem, you should find that AKE equals -85.1 J.O 0.304 m/s0.253 m/s0.292 m/sO 0.181 m/s0.219 m/s
