O moves downward with increasing speed.
A large sculpture of mass 2,400 kg was being transferred from the 3rd floor to the ground floor of the National Museum using a cable. It was uniformly decelerating for a height of 8 m until it reaches the ground floor. If the tension on the cable is 23,500 N, what is the initial speed of the sculpture as it is lowered down?
In the absence of air resistance, if a ball is thrown vertically upward with a certain initial speed, on returning to its original level it will have the same speed. When air resistance is a factor, will the ball be moving faster, the same, or more slowly than its throwing speed when it gets back to the same level? Why? (Physicists often use a “principle of exaggeration” to help them analyze a problem. Consider the exaggerated case of a feather, not a ball, because the effect of air resistance on the feather is more pronounced and therefore easier to visualize.)

- An airplane in flight is subject to an air resistance force proportional to the square of its speed v. But there is an additional resistive force because the airplane has wings. Air flowing over the wings is pushed down and slightly forward, so from Newton’s third law the air exerts a force on the wings and airplane that is up and slightly backward. The upward force is the lift force that keeps the airplane aloft, and the backward force is called induced drag. At flying speeds, induced drag is inversely proportional to v 2 , so that the total air resistance force can be expressed by Fair = av2 + b/v2 where a and b are positive constants that depend on the shape and size of the airplane and the density of the air. For a Cessna 150, a small single-engine airplane, a = 0.30 N.s2 /m2 and b = 3.5×105 N.m2 /s 2 . In steady flight, the engine must provide a forward force that exactly balances the air resistance force. 1.
