Answer 1

Answer:

Tennis ball was in the air for 1.77 sec

Explanation:

Xavier throws a tennis ball to his friend Olaf at a 20° angle relative to the ground with an initial velocity of 18 m/s.

=> Horizontal Speed = 18 Cos20°

= 16 .914 m

Distance Covered = 30 m

Time Taken  = 30/16.914

=> Time = 1.77 sec

Tennis ball was in the air for 1.77 sec
