Problem 64 of 7
Create and solve a quadratic equation from motion context Height h(t)=-16t^2+64t. Find when height is 0 after launch.
Using a hint is okay. It just tells the trainer to give you a little more review.

identify height equation and solve for time or height condition.
Hidden until you reveal it.
Motion context must use a quadratic height model and require solving for time or condition.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Set the height expression equal to the target height.
2. Solve the resulting quadratic.
3. Interpret and reject times outside the context.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Negative time or initial-time solution if context asks after launch.
