Question
A boy standing in a ditchthrows a baseball upward toward his father. The ball leaves hishand at ground level, with an initial speed of 16.0 m/s,at an angleof q = 43°, from the horizontal. The boy's father reaches up and catches the ball over his head, ata height of 2.0 m above the ground. The father catches the ball onits way down (as shown in the Figure). Calculate how long the ballis in the air. ( g = 9.81 m/s2)Incorrect. Tries 2/10 PreviousTries

Explanation / Answer
h = vy0 t - 1/2 g t2 vy0 = 16 * sin 43 = 10.91 m/s 2 = 10.91 t - 4.9 t2 Solving the quadratic I get 2.02 and .202 sec 2.02 sec would be the answer for the ball on its waydown Solving the quadratic I get 2.02 and .202 sec 2.02 sec would be the answer for the ball on its waydownRelated Questions
