Answer:
1 m/
Explanation:
The Net Force refers to the sum of all forces acting on an object. Hence,
Net Force of box
= 20 + (-9.0) [It is -9.0 as both forces are in different directions]
= 11.0 N
We also need to know that the net force on an object is equal to the product of the mass of the object and the acceleration of the object. Hence,
11.0 = 12.0
= 1 m/
(nearest whole number)
