An ice sled powered by a rocket engine starts from rest on a large frozen lake and accelerates at +34 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 16,600 ft and the total time is 90 s, find the following. (a) the times t1 and t2 t1 = s t2 = s (b) the velocity v v = ft/s at the 16,600-ft mark, the sled begins to accelerate at −24 ft/s2. (c) what is the final position of the sled when it comes to rest? ft (d) how long does it take to come to rest? (give the amount of time after the sled begins to decelerate t3, and the time for the entire trip ttotal.) t3 = s ttotal = s

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
