Answer: 11.4
Step-by-step explanation:
area of rect. = 24
area of circle (half circle+half circle = full circle) = pi*r^2 = pi*(2*2) = pi*4 = about 12.57
2 = radius since 4 = diameter
24-12.57 = 11.43
round = 11.4
Force= mass*acceleration.
-25= 10x
Divide both sides by 10
-2.5=x
Final answer: The acceleration is -2.5 in the direction of the force.
