Question

A ball is thrown with an initial velocity of 8.5 m/s at an angle of 30.0 degrees from the horizontal. How long the ball is in flight? (assume g = 9.81 m/s2)

Answer 1

given, Vo = 8.5 mle Vo initial ve velocity , vor congle with horizmlad (- 30.0 g=9 Then the time, that the ball in flight at the total time of - 9.81 ml? flight and and og • given, by the following mation shown above, for the equation the projectile ta Qo sin (O) Oo Bubekaduting the time of flight. respective value, + 2(8.5 Mb) 4in (30) (9.81 me? = 0.866 gec t=0.866 sec

Comment

The ball takes t=0.866s to flight
