During soccer practice, maya kicked a soccer ball 37° off the ground at 25 m/s. what was the ball's speed 2.2 s after she kicked it?

Answer

3.44 m/s

Explanation

The motion apply the equations of Newton's law of motion. The ball is acceleration is -9.8 m/s² (acceleration due to gravity. It is negative because the ball is going against gravity, so it is decelerating).

The first equation of Newton's law of motion is;

V = U + at

Where V is the final velocity, U is the initial velocity, a is acceleration and t the time taken.

V = 25 + (-9.8 × 2.2)

    = 25 - 21.56

     = 3.44 m/s

the answer is 12 as i may remember
