Question

To calculate the time it takes for the rock to reach the ground when dropped from the Taipei World Financial Center, you would need to use the kinematic equation. The correct answer depends on the assumptions made about the initial conditions and neglect of air resistance.

Answer 1

To calculate the time it takes for a rock to reach the ground when dropped, we can use the kinematic equation. The specific answer depends on the initial conditions and neglect of air resistance. By considering the vertical displacement and using the equation d = v0t + 0.5at^2, we can solve for the time.

Step-by-step explanation:

When calculating the time it takes for a rock to reach the ground when dropped from a certain height, we can use the kinematic equation. However, the correct answer depends on the assumptions made about the initial conditions and the neglect of air resistance. In this case, the rock rises and then falls to a final position 20.0 m lower than its starting altitude. We can find the time for this by using the equation:

d = v0t + 0.5at2

Where d is the vertical displacement, v0 is the initial velocity (which is 0 when the rock is dropped), a is the acceleration due to gravity, and t is the time.
