(a)

Answer to Problem 1SP
The velocity of the ball at the high point is
Explanation of Solution
Given Info: A ball is thrown up with initial velocity
The velocity is defined as the rate of change of displacement of the object.
The ball is thrown up. The displacement is upwards but it is acted upon by the acceleration due to gravity which is acting in the downward direction. This means that the velocity decreases as it goes up. This means that velocity becomes zero as the ball is at the highest point. Therefore, the velocity is
