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

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 7.4 m/s , and it travels a distance of 4.0 m .

Part A: 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.

Part B: What was its time of flight?

For Part A, I got 22.9 ∘ to the horizontal, but it's marking it incorrect. I don't know what I'm doing wrong.

Answer 1

Answer #1

R = 4 m , u = 7.4 m/s

R = u^2sin(2theta)/g

4 = 7.4^2sin(2*theta)/9.8

theta = 23 degrees, 67 degrees

T = 2usin(theta)/g

T = 2*7.4*sin(23)/9.8

T = 0.59 s, 1.4 s

In basketball, hang is an illusion in which a player seems to weaken the gravitational acceleration while in midair. The illusion depends much on a skilled player's ability to rapidly shift the ball between hands during the flight, but it might also be supported by the longer horizontal distance the player travels in the upper part of the jump than in the lower part. If a player jumps with an initial speed of Vo = 6.00 m/s at an angle...

In a game of basketball, a forward makes a bounce pass to the center. The ball is thrown with an initial speed of 4.6 m/s at an angle of 15 ? below the horizontal. It is released 0.90 m above the floor. What horizontal distance does the ball cover before bouncing? While doing this problem, I came across the quadratic equation. The actual answer for t is .32 seconds. However, once I completed my quadratic equation I got t=.170. I...
