Question

Unsure how to do problem 2.

For objects that are dropped from rest, use the initial speed of 0 m/s. For objects shot upwards, use the angle of 89 degrees. While this creates a very small error because it's not directly upwards, it allows you to see both the path up and down. 1. Starting from a height of 12 m, how long does it take for the cannon ball to drop to the ground? Use an initial speed of 0. 1 h 12 m 89 12m = (23)(1) (9.8- 12m = (4.9) (1)? Time 1.56 s 2.449 s? = t? Range Om Height Om 1.56s = t Initial Speed 0 mis 2. Set the cannon to fire upwards at 10 m/s initially (still at an initial height of 12m). a. How much time does it take to reach its peak?
