A Problem of Soccer Ball Kicked at an Angle

Calculation of Initial Velocity in the x-Direction

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

Answer: 72.8 m/s

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.

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?

72.8 m/s
