Projectile Motion Calculation

What is Rosa most likely trying to find using the formula (vi cos)t?

Based on the given formula that Rosa uses to do a calculation, the value that Rosa is most likely trying to find is:

A. Velocity

B. Acceleration

C. Power

D. Displacement

Answer:

The horizontal displacement of a projectile launched at an angle.

Explanation:

If the formula used by Rosa is vi cosθ where vi is the initial speed of the object or the velocity with which the object is thrown. There are two components of velocities i.e. horizontal and vertical. If θ is the angle with horizontal. We know that the distance travelled is given by:

d = vi cosθ × t

So, Rosa is trying to find the horizontal displacement of a projectile launched at an angle.
