Find the magnitude of the velocity relative to the earth

Reference no: EM13507545

In an action-adventure film, the hero is supposed to throw a grenade from his car, which is going 94.0 km/h, to his enemy's car, which is going 112 km/h. The enemy's car is 16.6 m in front of the hero's when he lets go of the grenade.

1. If the hero throws the grenade so its initial velocity relative to him is at an angle of 45 degrees 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.

2. Find the magnitude of the velocity relative to the earth.
