Can someone please help with the equations used and how to solve?
oblem 4.44 c) 10 of 11 What was the initial direction of the ball? Express your answer using two significant figures. If there is more than one answer, separate them by a comma. A player passes a basketball to another player who catches it at the same level from which it was thrown The initial speed of the ball is 7.5 m/s, and it travels a distance of 4.8 m 0] to the horizontal Submit Incorrect: Try Again: 6 attempts remaining: no points deducted Your answer does not have the correct number of comma-separated lerms Part B Express your answer using two significant figures. It there is more than one answer, separate them by a comma.Explanation / Answer
a) Horizontal range, R = v02 sin (2 theta) / g
sin (2 theta) = R g / v02
sin (2 theta) = 4.8 * 9.8 / 7.52
sin (2 theta) = 0.836
theta = 28.4 deg
b) Time of flight = 2 v0 sin theta / g
= (2 * 7.5 * sin 28.4) / (9.8)
time of flight = 0.727 s
