Question

A ball is traveling 24° above the horizontal at a speed of 12 m/s. What is the vertical component of its speed? 5.3 m/s 0 4.9 m/s 23.5 m/s 11.0 m/s

Answer 1

Answer:

4.9 m/s

Explanation:

Let v = speed of the ball = 12 m/s

θ = Angle at which the ball is traveling = 24°

As the ball is traveling at an angle there will be two components. One horizontal component and one vertical component.

Vertical component of speed

$v_y=vsin\theta\\\Rightarrow v_y=12\times sin24\\\Rightarrow v_y=4.88\ m/s$

∴ Vertical component of its speed is 4.9 m/s
