In an action-adventure film, the hero is supposed to throw a grenade from his car, which is going 80.0 , to his enemy's car, which is going 120. The enemy's car is 14.2 in front of the hero's when he lets go of the grenade. The hero throws the grenade so that its initial velocity relative to him is at an angle of 45.0 above the horizontal. The cars are traveling in the same direction on a level road. You can ignore air resistance.
