Question

What is the net force and acceleration of a ball of mass 0.750 kilograms that is subjected to forces of 11.00 newtons and 7.00 newtons from opposite directions?

Answer 1

M = 0.75kg
F1 = 11N
F2 = 7N

Because forces are in opposite direction, the ball will accelerate in direction of force that has bigger amplitude. 

F = m*a
a = F/m
a = (F1-F2)/m
a = 5.333 m/s^2
