To calculate the force on the ball, we can use Newton's second law of motion, which states that force (F) is the product of mass (m) and acceleration (a): \( F = m \times a \).
Substituting the values, we have \( F = 4.75 , \text{kg} \times 1.5 , \text{m/s}^2 = 7.125 , \text{N} \), so the force on the ball is 7.125 N.
