A 736-lb object is launched from the ground with an initial
upward velocity of 60 ft/sec. The atmosphere resists the motion of
the object with a force of 3 lb for each ft/sec of speed. Assuming
that the only other force acting on the object is gravity, find the
time it takes for the object to reach its maximum height:

3. A 180-Ib person jumps out of an airplane with initial upward velocity of 5 ft/s at a height of 3000 ft (assuming the air resistance is proportional to its falling speed). The air resists the body's motion with a force of 2 lb for each ft/s of speed. Assuming the constant gravity is 32 ft/s2. 1. find its velocity v = v(t) 2. find its terminal velocity 3. find the distance of falling x = x(t) 4. find the...
