Explanation:
Power is defined as the work done per unit time or
Density is mass per unit volume
remember
p= m/v where v is vol, m is mass and p is density
So you can have a understanding of what you are doing and figure out your overall goal
Explanation :
Displacement refers to the distance between the final and the initial position. Hence the displacement of the ball will be the difference between the initial and the final displacement.
Let the initial position be 0.
Final position = 8 cm
So the difference between initial position and final position = 0 – 8 = - 8 cm.
So the billiard ball comes to rest 8.0 cm behind its orbital position.
