If the snowball takes 0.65 seconds to reach the smokestack, what is its velocity?

15 m

Smokestack

Knoll

* 4.5 m

Level ground

9.8 m/s

17 m/s

23 m/s

O 6.9 m/s

Question

What is the horizontal component of velocity at the instant the ball is thrown?

Answer:

23 m/s

Explanation:

Velocity is given by diatance per unit time. In this case, the horizontal distance is 15 m and time is given as 0.65 s hence substituting the above figures for velocity, we obtain that v=23/0.65=23.076923076923 m/s

Rounded off, the horizontal velocity component is approximately 23 m/s
