The acceleration due to gravity on Earth is 9.81 m/s² [down]. A hockey puck was launched from the ice with a velocity of 50.0 m/s [up]. Assuming no friction, determine the velocity of the puck at its maximum height.

Answer:

0 m/s.

Explanation:

When an object is shot up into the air the only force acting on it is gravity while neglecting wind. As the gravity is acting on the object it keeps decelerating till its velocity becomes 0 after which it can go no further. The maximum height of the object is at this point.

So, at its maximum height the velocity of the puck will be zero.
