Consider a rock that is thrown off a bridge of height 11 m at anangle ? = 22° with respect to the horizontal as shown in the figureabove. If the initial speed the rock is thrown is 13 m/s, find thetime at which the rock lands.
I have found the following so far, but no matter what equations Itry to find total time I keep getting told I have the wrong answer(all the others are correct though):
Time at maximum height: 0.4969s
Maximum height reached by rock: 12.21m
I've tried 1.995, 1.910, 2.152, & 0.9938 as answers for time atwhich rock lands using different equations, but all were incorrect.
