What happens when a ball is thrown vertically in upward direction?

$</p><p></p><p>\huge \sf\underline\color{blue}{Solution}\dag$

During ascent ball is going upward therefore its position is positive. Now , though the velocity is decreasing but its direction is upward i.e. positive. Ball is moving under the effect of gravitational acceleration , which is always acting vertically downwards so it is negative.

During ascent ball is going upward therefore its position is positive. Now , though the velocity is decreasing but its direction is upward i.e. positive. Ball is moving under the effect of gravitational acceleration , which is always acting vertically downwards so it is negative.During the upward motion the speed of body decreases and will be zero at the highest point (since gravitational force acting downward), afterward the body start downward motion and its speed increases.
