Determine the value of impulse from this graph of momentum vs time

Answers

Answer 1

Answer:

Answer:

The value of impulse is 9 N-s.

Step-by-step explanation:

The momentum vs time graph shows the impulse

Impulse :

Impulse is the product of force and time.

In mathematical terms,

$I= F\Delta t$

Where, F = force

t = time

According to graph,

Impulse $I = F\cdot t$ =total area

$I=(1)/(2)*3*6$

$I=9\ N-s$

Hence, The value of impulse is 9 N-s.

Answer 2

Answer:

Answer:

try 12 Newton seconds

Step-by-step explanation:

I think it's going to be 12 because if you find the slope of the first line you get 1 Newton and the slope of the second line is -1 Newton's. so that means there is a change of -2 newtons. so if you multiply -2 Newton's by the 6 seconds you -12 Newton seconds. let me know if this is correct as it's been a while since I've done this type of stuff.

What is the value of 4^6 over 4^6 ?

Answers

Remark
If you know the answer to

6/6 then you know the answer to 4^6 / 4^6

Both are equal to one. You could expand 4^6 to get a numerical answer.

4^6 = 4096

4096 / 4096 = 1

Edit
See comment posted by the asker.
Well you could do it one of 2 ways.

4 * 4 * 4 * 4 * 4 * 4
4 * 4 * 4 * 4 * 4 * 4 * 4 * 4 You can do the cancellation to get

1
4*4

1/16 That's one way

or

you could do this as

4^6
4^8

1/(4^ (8 - 6) ) = 1/4^2
1 / 4^2 = 1/16 <<<<<< answer

Rule
When the bases are the same and the powers are different and you are dividing you can always subtract the powers.

isn't it just one since
_4^6_
4^6
simplifies to _4096_
4096
which equals one?
