A ball is thrown upward with an initial velocity from the surface of the earth.
The motion of the ball is affected by a drag force equal to ( where m is
mass of the ball, v is its instataneous velocity and is a constant). Time taken
by the ball to rise to its zenith is:
Newton's 2nd Law -
Therefore
- wherein
in C.G.S & S.I
