A toy rocket is launched vertically upward from a 12-foot platform. How long will it take the rocket to reach the ground?

Answer :

It will take approximately 0.863 seconds for the toy rocket to reach the ground when launched vertically upward from a 12-foot platform.

The time it takes for a toy rocket to reach the ground depends on its initial velocity and acceleration due to gravity. Let's assume that the rocket is launched with an initial velocity of 0 feet per second (since it's launched vertically upward) and the acceleration due to gravity is approximately 32.2 feet per second squared.

To identify the time it takes for the rocket to reach the ground, we can use the kinematic equation:
distance = initial velocity * time + 0.5 * acceleration * time²
Since the rocket is launched vertically upward and reaches the ground, the distance it travels is the height of the platform, which is 12 feet. We can plug the values into the equation and solve for time:
12 = 0 * t + 0.5 * 32.2 * t²

Simplifying the equation, we have:
12 = 16.1 * t²
Dividing both sides by 16.1, we get:
t² = 0.744
Taking the square root of both sides, we calculate:
t ≈ 0.863 seconds
