easy to use kinetic energy
(1/2)m v^2 + 7.31 = (1/2)m Vfinal^2
.324 (1.31)^2 + 14.62 = .324 Vf^2
A .324 kg air track glider moves linearly with an initial speed of 1.37 m/s.In order to increase the speed of the mass, 7.31 J of work are done. What is the final speed of the glider? (Ignore the negligible friction)
