Answer

Explanation:

Step1: Calculate net - force

Assume the forces acting on the ball are (F_1 = 31.20) N and (F_2 = 27.00) N in opposite directions. The net - force (F_{net}=F_1 - F_2). Let (F_1) be the larger force. So (F_{net}=31.20 - 27.00=4.20) N.

Step2: Calculate acceleration

According to Newton's second - law (F = ma), where (m = 0.750) kg and (F = F_{net}=4.20) N. Then (a=\frac{F_{net}}{m}). Substitute the values: (a=\frac{4.20}{0.750}=5.60) m/s².

Answer:

The net force is 4.20 newtons, and the acceleration is 5.60 m/s². Since this answer is not among the given options, there may be an error in the problem - setup or options provided. But if we assume there is a rounding or data - entry issue, the closest option based on the net - force value of 4.20 N (assuming acceleration values are rounded) is B. The net force is 4.20 newtons, and the acceleration is 5.50 m/s². So the answer is B.
