A ball is tossed directly upward at an initial speed of 5.7 meter per second and is caught when it falls back down to the thrower's hand, at exactly the similar height from which it was thrown.
Obtain what is the maximum height does the ball reach above the thrower's hand? Determine how much total time is the ball airborne?
Determine the average speed for the ball journey?
Determine the average velocity for the ball's journey?
