# Position vs time graph

Throw a projectile vertically upwards by moving the bolt point along the curve.

Describe the motion of the ball from the moment it leaves the thrower's hand.
What is the initial velocity of the projectile?
What happens to the velocity once the project leaves the thrower's hand?
What is the velocity of the projectile at the maximum height?
What happens to the velocity of the projectile between time (2s-4s)
What the final velocity of the projectile
What is the gravitation acceleration at the maximum height
