Given data:
The initial velocity,
The function for the position of the ball is,
Solution for (a):
The function for the position of the ball is,
The velocity of the ball at the maximum height is zero, therefore, differentiate the expression above with respect to time to determine the time required for the ball to reach maximum height,
Here, s is constant, therefore,
Substitute and solve for t
Therefore, the time required for the ball to reach the maximum height is 3 seconds.
Step by step
