Ball thrown at wall: height and velocity components

[tjbateh]

Homework Statement

You throw a ball toward a wall at speed 32.0 m/s and at angle θ0 = 38.0° above the horizontal (Fig. 4-35). The wall is distance d = 15.0 m from the release point of the ball. (a) How far above the release point does the ball hit the wall? What are the (b) horizontal and (c) vertical components of its velocity as it hits the wall?

Homework Equations

The Attempt at a Solution

For part B, I got 25.22 m/s..
When I put in part C as 19.7, which is what i thought it was, it said it's wrong.
What should I do from here?

 

[Doc Al]

While the horizontal velocity remains constant, the vertical velocity changes as the ball moves. You need to know what time the ball hits the wall in order to find the vertical component of velocity.

Solve the problem step by step using the principles of projectile motion and kinematics.
