In the latest Indian Jones film, Indy is supposed to throw a grenade from his car, which is going 99.0 km/h , to his enemy's car, which is going 115 km/h . The enemy's car is 17.0 m in front of the Indy's when he lets go of the grenade. A If Indy throws the grenade so its initial velocity relative to him is at an angle of 45 ∘ above the horizontal, what should the magnitude of the initial velocity be? The cars are both traveling in the same direction on a level road. You can ignore air resistance. B Find the magnitude of the velocity relative to the earth.
