Part A- If neither driver brakes and the cars collide at the intersection and lock bumpers, what will the magnitude of the velocity of the cars be immediately after the collision? Express answer using two sig figs.
Part B- What will the direction of the velocity of the cars be immediately after the collision? Express answer using two sig figs.
Part C- What percentage of the initial kinetic energy will be lost in the collision? Express answer using two sig figs.
