To calculate the force exerted by your hand on the ball, you can use Newton's second law of motion, which states that force equals mass times acceleration (F = ma).
In this case, the mass of the ball is 0.06 kg and the acceleration is 13.7 m/s2. So, the force exerted by your hand on the ball can be calculated as:
F = (0.06 kg)(13.7 m/s2)
F = 0.822 N
Therefore, the correct answer is 0.82 N.
