A player passes a basketball to another player who catches it at the same level

Question

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 7.1 m/s, and it travels a distance of 3.9 m. 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. Theta = ______ to the horizontal Part B What was its time of flight? Express your answer using two significant figures. If there is more than one answer, separate them by a comma. T = ______ s

Explanation / Answer

Here,

initial speed , u = 7.1 m/s

distance , d = 3.9 m

part A) let the initial angle of the ball is theta

d = u^2 * sin(2 * theta)/g

3.9 = 7.1^2 * sin(2 * theta)/9.8

solving for theta

theta = 24.7 degree , 65.3 degree

the initial angle is 24.7 degree

part B)

time of flight = 2 * u * sin(theta)/g

time of flight = 2 * 7.1 * sin(24.7 degree)/9.8

time of flight = 0.605 s

the time of flight is 0.605 s
