A child throws a ball with an initial speed of 8.0 m/s at an angle of 40° above the horizontal. The ball leaves her hand 1.0 m above the ground. At what angle below the horizontal does the ball approach the ground? Hint: Another multiple part problem. 1) Compute the x- and y-components of the initial velocity vector. 2) Draw a picture of the trajectory and label it with the initial and final positions. 3) Solve the y position equation of motion for the time. Choose the physical root. 4) Compute the final y-velocity just as the ball hits the ground. The final x-velocity is the same as it was initially. 5) Compute the angle of the final velocity vector from its components. O 40° 35° O 42° O 48° O o oO

A child throws a ball with an initial speed of 8.0 m/s at an angle of 40° above the horizontal. The ball leaves her hand 1.0 m above the ground. At what angle below the
horizontal does the ball approach the ground?
Hint: Another multiple part problem.
1) Compute the x- and y-components of the initial velocity vector.
2) Draw a picture of the trajectory and label it with the initial and final positions.
3) Solve the y position equation of motion for the time. Choose the physical root.
4) Compute the final y-velocity just as the ball hits the ground. The final x-velocity is the same as it was initially.
5) Compute the angle of the final velocity vector from its components.
