<h2>Explanation:</h2>An object is launched vertically upward from a 25 foot platform and is modeled by the following function:
So this is the equation of a parabola because the object is a projectile so it follows the Projectile Motion.
The object fall back to the ground when so:
Since time can't be negative, we only choose the positive value. therefore:
<em>The object fall back to the ground after 1.64 seconds</em>

Set up the equation as follows:
150x represents the dog's speed, 100x represents the squirrel's speed, and 200 represents the distance the squirrel has on the dog. x is the amount of minutes that elapse.
Subtract 100x from both sides.
Divide both sides by 50.
It will take the dog 4 minutes to catch up with the squirrel.
