What are the three most common ways for energy to leave a system during a collision?
An isolated system consists of two objects, A and B, moving without friction along a horizontal x-axis. The figure shows the initial masses and speeds of these objects. 7.00 m s-¹ 2.00 kg A Check 5.00 m s-¹ Final kinetic energy initial kinetic energy = || 3.00 kg The two objects then suffer an inelastic collision, after which they remain stuck together, traveling as a single composite object, confined to the x-axis. None of these objects rotates. - B What is the difference between the final kinetic energy of the composite object and the total initial kinetic energy of A and B? Give you answer by entering a number, specified to an appropriate number of significant figures, into the empty box. V J.
