How would you find the terminal speed of an object once it reaches terminal velocity, using only the position and time data?
(ex:)
| Time(s) | Postion(m) |
| 5.58 | 0.647 |
| 5.62 | 0.703 |
| 5.66 | 0.765 |

18. Jonah throws a rock off the Empire State Building, and it quickly reaches terminal velocity. Find the terminal velocity of the rock as it falls vertically, given the following information: drag coefficient = 0.75; air density = 1.2 kg/m3; cross-sectional area of the rock = 5e-5 m²; mass of the rock = 27 g.

3. In lecture, we derived the detailed time-dependence of the downward speed of a falling object with a kv frictional force. Perform the analogous derivation of the time-dependence of the speed v(t) for a falling object subject to air drag, Farag-DV2 a. First use Newton's second law for a vertically falling mass m to find an equation relating dt to v(t). b. Integrate this equation. Let the initial velocity be v(0) = 0 at t = 0. c Make a...
1.) An object is dropped from a height of 200 m. What is its velocity as it reaches the ground? How long time) before it reaches the ground? 2.) An object is fired into a projectile with an initial velocity of 250 m/s at an angle of 60° with respect to the horizontal. What is maximum height it reaches? What is the maximum horizontal distance it reaches? What is the time of flight of the projectile? What is its velocity...
An object falls from a position of rest and reaches an instantaneous speed of 3 m/s. How far will it have dropped? The acceleration of gravity is 9.8 m/s^2. Answer in units of m.

A student measures the velocity of an object moving along a track. At time t = 0 s, the object is moving at a constant 4.0 m/s in the positive x-direction. At time t = 3.0 s, the object begins to slow, stops at t = 5.0 s, and then moves in the opposite direction. At t = 6.0 s, the object as reached a speed of -2.0 m/s. It moves at this speed until the student quits taking data...
DNA Electrophoresis:
a) The DNA reaches terminal velocity quickly during
electrophoresis and stays in that state. Solve for the terminal
velocity for the viscous and drag force case.
b) Which of these terminal velocities depend on the size of the
DNA molecule? How does the terminal velocity change with molecule
size? ( does terminal velocity go up or down as the size gets
bigger?)
c) Based on your calculations is the resistive force on a DNA
molecule during electrophoresis best...
An object moves with constant acceleration. At t = 2.50 s, the position of the object is x = 2.00 m and its velocity is v = 4.50 m/s. At t = 7.00 s, v = -12.0 m/s. Find: (a) the position and the velocity at t = 0; (b) the average speed from 2.50 s to 7.00 s, and (c) the average velocity from 2.50 s to 7.00 s.
An object is launched with a speed v0 = 80.0 m/s and with an angle α0 = 60º with respect to the flat surface from which it was launched at a place where g = 9.80 m/s^2. a) Calculate the position (x, y) of the object when t = 4.00s. b) Calculate the magnitude and direction of its velocity when t = 4.00s. c) Determine the time at which the object reaches its maximum height and the value of said...
An object's velocity as a function of time is shown in the plot below. The object begins at position s = 10 m at t = 0 s. What is the object's total displacement at t = 7 s? What is the object's position at t = 7 s? What is the total distance the object Innis moved between t = 0 and t = 7 s. What is the acceleration of this object at t = 1, 3, 5...
