Dec 29, 2020 · A 2,000 pound bullet fired from a 16" naval gun will (assuming it possible to fire the gun straight up) free fall at a very high velocity due to its great weight (mass) relative to its cross-sectional area. A "BB" (iron core ball 0.177" dia.) will fall at a relatively low velocity, probably not enough to do any injury to other than the eye.

Sep 08, 2020 · Equation of motion, mathematical formula that describes the position, velocity, or acceleration of a body relative to a given frame of reference. Newton’s second law, which states that the force F is equal to the mass m times the acceleration a, is the basic equation of motion in classical mechanics.
g=-32 ft/sec^2 ( we took it negative because it's free fall and for free fall the value of g is a negative value). v=-96 ft/sec. Plugging values of v and g in given formula, we get . t= -96/2(-32) t= -96/-64. Dividing -96 by -64, we get . t=1.5 seconds. Therefore, it take 1.5 seconds to reach the final velocity of -96 feet per second.
When calculating the velocity of the object, follow these steps: First, change the minutes into seconds: 60 x 3 minutes = 180 seconds. Then use the velocity formula to find the velocity. v = distance / time = 500m / 180 seconds = 2.77 m/sec. Using a velocity calculator or an initial velocity calculator makes this task easier.
Mar 30, 2020 · The basic formula for velocity is v = d / t, where v is velocity, d is displacement and t is the change in time. Velocity measures the speed an object is traveling in a given direction. Velocity is the change in position of an object within a specific time frame.

Using Calculus To Derive The Freefall Formula. The Position Equation (also known as the freefall formula) S = -16t 2 + V o t + S o is often cited in college algebra textbooks. In this formula, S represents the height (in feet) of an object thrown into the air at any time t (in seconds) where V o is the velocity at which the object is thrown upward (or downward) and S o is the height of the ...
Knowing the acceleration, we can determine the velocity and location of any free falling object at any time. The remarkable observation that all free falling objects fall with the same acceleration was first proposed by Galileo Galilei nearly 400 years ago.
