One of the construction workers likes to listen to music on the job. Unfortunately, he also has a
bad habit of accidentally dropping his music player into the ravine! Luckily, his daughter is good
with physics and has built a safety balloon for his latest music player that will release after the
music player has been falling for 1 second,
The time it takes for the music player to fall from the bridge to the bottom of the ravine can be
modeled by the following equation:
where t is the amount of time since the construction worker dropped his music player.
will the safety balloon release in time?
1. first how long will it take for the music player to fall to the bottom of the ravine? solve the equation and find the values of t. (2 points: 1 point for each value)
2. your solution produces two roots, but you should make sure that both times are valid. Checks your work by plugging each root back into the original equation and simplifying each expression. identify the answer that is actually a solution (2 points: 1 point for each time)
8. will the music player land safely? how do you know? (1point)
