PLEASE HELP URGENT URGENT: Wile E. Coyote is trying to catch the Roadrunner, as usual. Wile is at the base of a 40 m cliff, and spots the Roadrunner at the top. His insane plan is to shoot himself upwards with a bow, and hope that it launches him high enough. Incredibly, he makes it exactly 40 m high, but by then, the Roadrunner is gone, and he falls back to the ground empty-handed.

How fast did the bow launch Wile into the air?

How much time was Wile in the air?

In an experiment, how can i change human errors? be specific.

Aspring has a natural length of 8 m. if a 12-n force is required to keep it stretched to a length of 10 m, how much work w is required to stretch it from 8 m to 16 m? (round your answer to two decimal places.)

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
