Question

In an action-adventure film, the hero is supposed to throw a grenade from his car, which is going 98.0km/h , to his enemy's car, which is going 121km/h . The enemy's car is 14.6m in front of the hero's when he lets go of the grenade.

A. If the hero 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.

I did all my physics homework but this problem, the answer seems to escape me.

correct answer with explaination will be most appreicated.

Thanks in advance

Explanation / Answer

Okay. Let's make this problem simple by letting v = vertical and horizontal velocities, since the grenade is being thrown at a 45
