Motion and Projectiles Homework-Due tommorow

Question

Extended Writing Task: Freefall

Two identical steel balls are released from rest above cylinders containing oil as shown in the diagram below.The balls travel vertically until they reach the bottom of the cylinder. The graph below is the velocity-time graph for steel ball A.

Diagram:
-steel ball A is above cylinder container 1 with oil filled to the top
-steel ball B is above cylinder container 2 which has oil filled to half way

Velocity-time Graph:
in the graph steel ball A has a curved line in which as the time goes on the velocity rate decreases but there is still more velocity with more time but less and less until a certain point where the reaction stops.At the end of the curved line there is a line going downwards.

Describe and explain how the motion of steel balls A and B will differ and why.Your answer should include:
-How the velocity and acceleration of steel ball A and B vary with time
-An account of the forces acting and their sizes
-A sketch of the velocity-time graph that would represent the motion of steel ball B (you may wish to draw this over the graph above)

Continue this task on lined paper writing with good English and attach it behind this sheet.

Write as much as you can.

Please help with the things I have to include as I'm stuck on this question

Answer 1

So

Describe and explain how the motion of steel balls A and B will differ and why.Your answer should include:
-How the velocity and acceleration of steel ball A and B vary with time
-An account of the forces acting and their sizes
-A sketch of the velocity-time graph that would represent the motion of steel ball B (you may wish to draw this over the graph above)

Answer 2

I can tell you the acceleration and velocity of B will the same as A until it hits oil, then acceleration slows to zero or close to zero, and velocity may even come to a cosntant.
Forces: Gravity, and in B, friction.
