A Tennis Ball Velocity Analysis

What is the vertical component of the velocity right before the ball hits the ground?

Answer: 20 m/s

Vertical Component of Velocity Calculation

Given:

Velocity = 40 m/s

Angle = 30°

Vertical component = V_y (sinθ)

Explanation:

Using the given data, we can calculate the vertical component of the velocity right before the ball hits the ground.

Substitute into the formula:

V_y = Velocity (sinθ)

V_y = 40 m/s (sin 30°)

V_y = 40 (0.5)

V_y = 20 m/s

Therefore, the vertical component of the velocity right before the ball hits the ground is 20 m/s.
