Final answer:

The height of the ball after four seconds is 640 feet.

Step-by-step explanation:

The equation given to calculate the height of the ball after t seconds is h = -16t² + 224t. To find the height of the ball after four seconds, we can substitute t = 4 into the equation:

h = -16(4)² + 224(4)

h = -16(16) + 224(4)

h = -256 + 896

h = 640

Therefore, the height of the ball after four seconds is 640 feet.
