Final answer:
To rank the throws based on time to hit the ground, the acceleration due to gravity is considered. Objects hitting the ground with delays of 3.2, 2.1, and 1.1 seconds indicate longer air times than one hitting simultaneously. Ranked from longest to shortest time, they are in the order of the delays presented.
Step-by-step explanation:
Ranking Throws Based on Time to Hit the Ground
To rank the throws based on the time it takes for the ball to hit the ground, we need to consider the acceleration due to gravity, which is always directed downwards (negative in this context). When an object is thrown upward, the acceleration will be opposite to its initial velocity, slowing it down until it stops at its peak height, and then accelerating it back downwards.
Regarding the scenarios provided:
- If Object 1 hits the ground 3.2 seconds after Object 2, it was in the air longer than Object 2.
- If Object 1 hits the ground 2.1 seconds after Object 2, this throw also took longer than Object 2 but less than the first scenario.
- If both objects hit the ground simultaneously, their times in the air were equal.
- If Object 1 hits the ground 1.1 seconds after Object 2, this throw was in the air slightly longer than Object 2.
Therefore, ranking the throws from longest to shortest time in the air:
- Object 1 with 3.2 seconds delay
- Object 1 with 2.1 seconds delay
- Object 1 with 1.1 seconds delay
- Object 1 hitting the ground simultaneously with Object 2
The vertical position table for a ball launched upwards would show that as the ball reaches a higher altitude, the time taken for it to fall back down would increase. This is due to the deceleration on the way up and acceleration on the way down at 9.80 m/s2, the value of gravitational acceleration (g).
