Question

A cannon fires a shell at 200 m/s at an angle of 30° to the horizontal. What is the vertical component of the velocity?

A. 173 m/s

B. -28.2 m/s

C. 100 m/s

D. -10.3 m/s

Answer 1

The correct answer is:

C. 100 m/s

Step-by-step explanation:

The vertical component of the initial velocity can be calculated using trigonometry. The given velocity is 200 m/s at an angle of 30° to the horizontal.

The vertical component can be found using the formula:

Vertical Component = Initial Velocity * sin(Angle)

Vertical Component = 200 m/s * sin(30°)

Vertical Component ≈ 100 m/s

So, the correct answer is:

C. 100 m/s
