Part 2Procedure: Collisions between freely moving carts are executed on the tracks. Frictionbetween the track and the carts are assumed negligible. The acceleration due to the forceof gravity is eliminated by restricting all motion to the horizontal plane ( i.e., levelling thetrack). The track will be levelled in advance by the lab instructor.Collision:Of six different possible collisions, two or three collisions will be assigned forexamining. For each collision set-up, record the mass of both carts using the balanceprovided.Determine the initial and final velocities for both carts from the graphs obtained andrecord all information in the table provided. An explanation as to how to read from thegraphs will be provided by the lab demonstrator.Cart 1Mass(kg)V i (m/s) V f (m/s) P i(kg m/s)P f(kg m/s)Cart 2Total momentum of Cart 1 and Cart 2(Σ)Compare the initial and final total momentum of the two-cart system.→ Has momentum been conserved?
