A Football Player's Final Velocity

What is the final velocity of the ball when it hits the ground, given that a football player kicks a ball at a 30° angle from the ground with an initial velocity of 15 m/s?

The final velocity of the ball can be determined by calculating the time of flight and using the equation of motion.

Calculation of Time of Flight:

Given: Angle = 30°, Initial velocity = 15 m/s, g = 9.8 m/s² We can calculate the time of flight using the formula: T = 2u sinθ / g Plugging in the values:
T = (2 * 15 * sin 30) / 9.8 T = 1.5 sec

Calculation of Final Velocity:

Using the equation of motion: v = u + gt Plugging in the values: v = 15 + (9.8 * 1.5) v = 29.7 m/s

Therefore, the final velocity of the ball when it hits the ground is 29.7 m/s.
