Question

A player passes a 0.600-kg basketball downcourt for a fast break. The ball leaves the player's hands with a speed of 8.50 m/s and slows down to 7.00 m/s at its highest point

Answer 1

i need somebody to explain to me , the situation above , in presence of air resistance and not

Answer 2

Explanation: It says that at its highest point the ball slows down to 7.00m/s while in the air. This is important to understand because if you don't have air resistance then an object when thrown and when its reaches its highest point in its trajectory, the velocity (speed) will normally be zero. So air resistance must be present if when the object is at its highest point its velocity is non zero.
