A boat weighs 64,000 lb. Its propellor produces a constant thrust of 50,000 lb and the water exerts a resistive force with magnitude proportional to the speed, with k = the boat starts from rest, find its velocity as a function of time, and find its terminal velocity. 3. 2000 lb-s/ft. Assuming that 4.3.3 (p. 160) v = 25(1 – e-†);25 ft/s

Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differentia…
