The women’s record for fastest serve is by Sabine Lisicki with 131 mph which is approximately 58.56 m/s. Suppose she hit the ball at a height of 2.6 meters above the court at an angle of 8 degrees below the horizontal.

a. How high will the ball be when it reaches the net which is 11.89 meters away from the baseline? Assume she hit the ball right above the baseline. Does it hit the net or cross over it if the net height is 0.91 meters at the center?

b. If she served the exact same way, but now with no net in front of her, how far from where she hit the ball would it land on the court?

c. How fast is the ball going right before it hits the court? Give the ball’s horizontal, vertical, and resultant velocity. With the resultant, make sure to give both its size and direction (angle and reference)
