75.0-kg fullback running east with a speed of $4.80\mathrm{m}/\mathrm{s}$ is tackled by a $93.0-\mathrm{kg}$ opponent running north with a speed of $3.00\mathrm{m}/\mathrm{s}$. (a) Explain why the successful tackle constitutes a perfectly inelastic collision. This answer has not boon gradod yet. (b) Calculate the velocity of the players immediately after the tackle. magnitude Find the total momentum of the two players before the collision and use conservation of momentum to find their moment after the tackle, $\mathrm{m}/\mathrm{s}$ direction Make sure you are using the correct components of the velocity when calculating the direction, ${}^{\circ }$ north of east (c) Determine the mechanical energy that disappears as a result of the collision. * Use the information you have thus far to calculate the initial and final kinetic energies. 3 Account for the missing energy.
