A soccer ball is kicked with a speed of 8.50 m/s at an angle of 26.0° above the horizontal. If the ball lands at the same level from which it was kicked, how long was it in the air? (Neglect air resistance.)

upward velocity at launch = 8.5*sin26° = 3.726 m/s
using the equation 0 = v - gt,
time taken to reach max ht. = v/g = 3.726/9.8 s
same time needed to come down

so time in air = 3.726/4.9

ans: 0.76 sec
