As per Newton's III law we can say that
Force applied by object 1 on object 2 is always equal in magnitude and opposite in direction of the force that object 2 apply on object 1.
So we can say it as
now here above question is based upon the same
if a bag of vegetables applied a force F = 22.5 N of the surface stand the the same surface will apply same magnitude of force in opposite direction on the vegetables bag
So our answer will be F = 22.5 N (upwards).

Explanation:
If a ball is released from rest and falls a distance x with acceleration a for a time t, the equation of position is given by:
(1)
For time t = 1s:
(2)
Solving the equation for a:
(3)
Using equation 1 for time t = 3s and equation 3:
