Amodel rocket is fired vertically upward from rest. its acceleration for the first three seconds is a(t)=60t, at which time the fuel is exhausted and it becomes a freely "falling" body. fourteen seconds later, the rocket's parachute opens, and the (downward) velocity slows linearly to -18ft/sec in 5 seconds. the rocket then "floats" to the ground at that rate. (a) determine the position function 's' and the velocity function v (for all times 't'). sketch the graphs of 's' and 'v'. (b) at what time does the rocket reach its maximum height, and what is that height? (c) at what time does the rocket land? use antiderivatives to solve the problem.

Acompany manufactures large valves, packed in boxes. a shipment consists of 1500 valves packed in 75 boxes. each box has the outer dimensions 1.2 x 0.8 x 1.6 m and the inner dimensions 1.19 x 0.79 x 1.59 m. the boxes are loaded on a vehicle (truck + trailer). the available capacity in the vehicle combination is 140 m3. each valve has a volume of 0.06 m3. - calculate the load factor on the box level (%). - calculate the load factor on the vehicle level (%). - calculate the overall load factor (%).
