Here we have a projectile motion. It is type of motion that is made of a vertical shot and a horizontal shot. This is how we will solve it.
Firste step is to find horizontal and vertical component of a speed.
\\ v_{0y} = v_{0} * sin \alpha [/tex]
We are given this information:
Angle is negative because it is below the horizontal.
VERTICAL SHOT
Time needed for a grenade to fall to the bottom of a building is given by a formula:
We used negative value for a speed because it is considered that upwards shot has positive value and downwards shot has negative value.
The grenade will not explode before it hits the ground.
HORIZONTAL SHOT
<span>The horizontal distance from the building at which the grenade will land is called range. The formula for a range is given by:
</span>
The grenade will hit the ground at distance of 47.89m.
