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. [br]What is the initial velocity of the projectile?[br]What happens to the velocity once the project leaves the thrower's hand?[br]What is the velocity of the projectile at the maximum height?[br]What happens to the velocity of the projectile between time (2s-4s)[br]What the final velocity of the projectile[br]What is the gravitation acceleration at the maximum height
