An ice sled powered by a rocket engine starts from rest on a large frozen lake and accelerates at +35 ft/s2. after some time t1, the rocket engine is shut down and the sled moves with constant velocity v for a time t2. if the total distance traveled by the sled is 16350 ft and the total time is 90 s. find the following. (a) find the times t1 and t2. t1 t2 (b) find the velocity v. ft/s at the 15750 ft mark, the sled begins to accelerate at -21 ft/s2. (c) what is the final position of the sled when it comes to rest? ft (d) what is the duration of the entire trip?

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.)
