Answer: The acceleration is 145.54 m/s^2
Explanation: The second Newton's law says that:
F = m*a
This says that the Force applied on an object is equal to the mass of the object times the acceleration of the object.
We know that the mass of the ball is 0.426kg and the force is 62N, so we have
62N = 0.426kg*a
a=62N/0.426kg= 145.54 m/s^2
62/.426=a
154.54= acceleration
