If the effects of atmospheric resistance are accounted for, a freely falling body has an acceleration defined by the equation a = 9.81[1 - v ^2 (10 ^-4)] m/s^2, where v is in m/s and the positive direction is downward. If the body is released from rest at a very high altitude, determine (a) the velocity when t = 5 s, and (b) the body’s terminal or maximum attainable velocity (as t S ).
An elevator in the Taipei 101 skyscraper can start fromrest and accelerate to a maximum speed of 16 m>s with a constantacceleration of 1.1 m>s2. Through what distance does the elevatormove as it accelerates to its maximum speed?
An object of mass m falls from rest under gravity subject to an air resistance proportional to its speed. Taking the y axis as positive down, show that the differential equation of motion is m(dv/dt) = mg − kv, where k is a positive constant. Find v as a function of t, and find the limiting value of v as t tends to infinity; this limit is called the terminal speed. Can you find the terminal speed directly from the differential equation without solving it? Hint: What is dv/dt after v has reached an essentially constant value? Consider the following specific examples of this problem.(a) A person drops from an airplane with a parachute. Find a reasonable value of k.(b) In the Millikan oil drop experiment to measure the charge of an electron, tiny electrically charged drops of oil fall through air under gravity or rise under the combination of gravity and an electric field. Measurements can be made only after they have reached terminal speed. Find a formula for the time required for a drop…
The upward normal force exerted by the floor is 620 N on an elevator passenger who weighs 650 N. What are the magnitude in (m / s2) and direction of the acceleration on the passenger?
On July 13, 1977, while on atest drive at Britain’s Silverstone racetrack, the throttle on DavidPurley’s car stuck wide open. The resulting crash subjected Purleyto the greatest “g-force” ever survived by a human—he deceleratedfrom 173 km>h to zero in a distance of only about 0.66 m. Calculate the magnitude of the acceleration experienced by Purley(assuming it to be constant), and express your answer in units ofthe acceleration of gravity, g = 9.81 m>s2.
For a mass m falling in air, we assume that the air resistance is proportional to the speed v (t): mv '(t) = mg - kv (t),where g is the acceleration of gravity and k is a positive constant that depends on the geometry of the object.What is v (t) given that v (0) = 0?

A pilot performs an evasive maneuver by diving vertically at 310 m/s. If he can withstand an acceleration of 8.0 g without blacking out at what altitude must he begin to pull out of the dive to avoid crashing into the sea?

You're an investigator for the National Transportation Safety Board, examining a subway accident in which a train going at 90 km/hkm/h collided with a slower train traveling in the same direction at 24 km/hkm/h . Your job is to determine the relative speed of the collision, to help establish new crash standards. The faster train's "black box" shows that it began negatively accelerating at 2.1 m/s2m/s2 when it was 52 mm from the slower train, while the slower train continued at constant speed. What do you report ?
For bodies that are falling, to achieve terminal velocity, what must happen to the acceleration of the body? a. The acceleration of the body is remains the same through time. b. The acceleration of the body must decrease over time c. The acceleration of the body must equal to the acceleration due to gravity. d. The acceleration of the body must increase over time.
As a raindrop falls through the atmosphere, its speed initially changes as it falls toward the Earth.
