Question

A soccer ball is kicked at an angle of 25 degrees with a total initial velocity of 80 m/s. What is the magnitude of the initial velocity in the x-direction?

Answer 1

72.8 m/s

Step-by-step explanation:

The problem asks for the x-component of the velocity.

We have the magnitude, we have the angle. We can calculate the x-component with the formula:

vx = v * cos(angle) = 80 m/s * cos(25°) = 80 m/s * 0.91 = 72.8 m/s
