Josh and Bradley each bought a carton of milk. Their cartons were the same except that Bradley's carton was taller than Josh's. Each boy drank 1/4 of his milk carton. Did the each drink the same amount of milk? Explain.

Answers

Answer:

No

Because Bradley's carton is taller than Josh's, Bradley would drink more milk.

Let us assume that Bradley carton has 100 quarts . If he drank 1/4, he would drink 25 quarts of milk. If Josh carton is 80 quarts full of milk, he would drink 20 quarts of milk. this example shows that they would not drink the same amount of milk

Step-by-step explanation:

A taller carton would contain more ounces of milk.

A force of 20,000 N is exerted for 5.00 s, on a 75,000 kg mass. What is the impulse of the force for this 5.00 s ?

Answers

Answer:

Check pdf

Step-by-step explanation:

The impulse of the given force is required.

The impulse of the force which is being exerted on an object of 75000 kg is 100000 Ns.

Impulse

F = Force exerted on a body = 20000 N

t = Time the force was exerted for = 5.00 s

When finding the impulse of a force the mass of the object the force is being applied to does not matter. The only thing that can affect the force is if another force is being applied by the object which here is not doing so.

Impulse is given by

[tex]J=Ft\\\Rightarrow J=20000\times 5.00\\\Rightarrow J=100000\ \text{Ns}[/tex]
