Question

Write the equation of motion when an object is free falling towards Earth or thrown vertically upwards

Answer 1

The equation for the time it takes an object that is thrown or projected downward to reach a given velocity is:

t = (v − vi)/g

where

t is the time in seconds (s)

v is the vertical velocity of the falling object in feet/second (ft/s) or meters/second (m/s)

vi is the initial vertical velocity the object has been projected downward in ft/s or m/s

g is the acceleration due to gravity; g = 32 ft/s2 or 9.8 m/s2
