Question

Draw a free body diagram for a skydiver (jumping from a tall building): right as they exit the building after they have been failing but not reached terminal velocity. After they have reached terminal velocity. Which diagrams have balanced/unbalanced forces, explain. Suppose you are sending on a very smooth surface, like a sheet of ice or a floor that is soapy. If you gave 2 objects that differed in mass (like a small child and an elephants) the same push, how would they move? What law tells you how they should move? How would you move in either case? If an object travel at constant speed does it have an acceleration? Explain.

Explanation / Answer

24)
Newton's II Law states,
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force.

So they would both move in the direction of Push.
Force = mass * acceleration.
a = F/m

There acceleration would depend on the mass, as the Force is same.
The one with a heavy mass will have smaller acceleration than one with the lighter mass.

So,
a Elephant < a small child.
Now,

Newton's III Law states,
For Every action there is allways an equal and opposite reaction.
So You Would move in the opposite direction of push.

25)
If an object travels at constant Velocity, It's acceleration = 0.

Acceleration = dvdt
As change in Velocity is zero for Constant Velocity, dv = 09
Therefore,
a = 0

There is no acceleration.
