construct a graph corresponding to the stone's vertical velocity, vy(t).

Sagot :

Graph corresponding to the stone's vertical velocity, vy(t) is slant line from 1st quadrant to 4th quadrant.

Assume, For time direction 0 to 2 seconds

V  = Vo - gt

At T = 2 sec; V = 0

so, 0 = Vo - 20

Vo = 20 m/s

From T = 2 sec to T = 6sec

V = 0 - gt = -10 t

hence

Velocity vs time graph is in figure.

An object's speed and direction on a vertical plane are referred to as vertical velocity. Vertical velocity can be used to describe a variety of objects, including coins dropped into wells by children and balls flung into the air. Gravity, which constantly acts on an item to change its velocity, is a crucial factor in vertical velocity. As the ball ascends, its speed will progressively slow until it eventually comes to a stop, modifies its course, and returns to earth. Anywhere along the ball's course, its velocity can be expressed as a number. The number's sign (positive or negative) indicates the ball's direction, and its value indicates the ball's speed.
