Two tanks are engaged in a training exercise on level ground. 1bc first tank fires a paint-filled training round with a muzzle speed of 250 m/s at 10.0° above the horizontal while advancing toward the second tank with a speed of 15.0 m/s relative to the ground The second tank is retreating at 35.0 m/s relative to the ground, hut is hit by the shell. You can ignore air resistance and assume the shell hits at the same height above ground from which it was fired. Find the distance between the tanks
(a) When the round was first fired and
(b) At the time of impact.
