Thank you for the opportunity to help you with your question!
20) Let's begin with the definitions:
a)Force: We can define force as push or pull on an object as a result of its interaction with another object.
b)Acceleration: Rate of change of velocity is known as acceleration.
c)Mass: Mass represents the amount of matter in an object.
d)Weight: It is the force exerted on body by gravity.
21)We have three figures:
Figure 1: To balance the force draw a force of 15N in downward direction.
Figure 2: To balance the force draw a force of 10N acting away from the object in right direction.
Figure 3: To balance the forces draw a 20N force upwards.
22) In the given figure:
Most KE: is at point C
Most PE: is at point A
PE=KE: is at point B
Greatest Mechanical energy: is at point A considering the friction
Energy transformation between A and D: At A it is purely PE but at D it is PE+KE
