A baseball is dropped from an altitude h = 196 ft and is found to be traveling at 92 ft/sec when it strikes the ground. In addition to gravitational acceleration, which may be assumed constant, air resistance causes a deceleration component of magnitude kv², where v is the speed and k is a constant. Determine the value of the coefficient k. Plot the speed of the baseball as a function of altitude y. If the baseball were dropped from a high altitude, but one at which g may still be assumed constant, what would be the terminal velocity v? (The terminal velocity is that speed at which the acceleration of gravity and that due to air resistance are equal and opposite, so that the baseball drops at a constant speed.) If the baseball were dropped from h = 196 ft, at what speed vg would it strike the ground if air resistance were neglected? Vg Answers: The drag coefficient, k= i The terminal velocity, Vt= Without drag, i i ft-1 ft/sec ft/sec

At one instant, a bicyclist is 50 m due east of a park's flagpole, going due south with a speed of 18 m/s. Then, 13 s later, the cyclist is 45 m due north of the flagpole, going due east with a speed of 13 m/s. For the cyclist in this 13 s interval, what is the displacement (m) and direction north of west, average velocity (m/s) and direction north of west and the average acceleration and direction north of east?
Determine an expression for the velocity vA of the cart A down the incline in terms of the upward velocity vB of cylinder B. If h = 1.93 m, x = 3.09 m, and vB = 3.14 m/s, what is vA?
An object is thrown from a level field with initial upward speed 17 m/s and forward speed 9.9 m/s. How far (in m) from its launch point is its landing place? You do not need to put the unit in the answer, just the number. As usual, ignore air resistance, etc; use the acceleration due to gravity as 9.8 meters per second squared.
Most important in an investigation of an airplane crash by the U.S. National Transportation Safety Board is the data stored on the airplane’s flight-data recorder, commonly called the “black box” in spite of its orange coloring and reflective tape.The recorder is engineered to withstand a crash with an average deceleration of magnitude 3450 g during a time interval of 6.49 ms. In such a crash, if the recorder and airplane have zero speed at the end of that time interval, what is their speed at the beginning of the interval?
Suppose the baseball is struck from the edge of a cliff such that y0 = 30 m and x0 = 0. The components of the initial velocity are v0x = 20 m/s and v0y = 0. What is the x coordinate of the baseball when it lands on the ground at y = 0? (Write only the numerical value rounded to a whole number and exclude the unit)

An unidentified flying object (UFO) is observed to travel a total distance of 19000 m, starting and ending at rest, over a duration of 4.23 s. Assuming the UFO accelerated at a constant rate to the midpoint of its journey and then decelerated at a constant rate the rest of the way, what was the magnitude of its acceleration? Express your answer in g s , where 1 g = 9.81 m/s^2.
