Can you please provide an image of the graph?
23) 560 cm
25) 3100 mg
27) 8.89 cm
29) 525 g
31) I can't see the measurement it needs to be converted to
The formula to find the magnitude of velocity is:
▲v= ▲M/m
▲v=Velocity Change
▲M=Momentum Change
m=Mass
Plug in the information;
▲v=345/5
The answer is 69
Answer:
The force is 272.73 newtons
Explanation:
We're going to use impulse-momentum theorem that states impulse is the change on the linear momentum this is:
(1)
Impulse is also defined as average force times the time the force is applied:
(2)
By (2) on (1):

solving for
:
(3)
We already know Δt is equal to 0.22 s, all we should do now is to find
and put on (3) (
the initial momentum and
the final momentum). Linear momentum is defined as
, using that on (3):
(4)
Velocity (v) are vectors so direction matters, if positive direction is the right direction and negative direction left
and
so (4) becomes:

(5)
Using (5) on (3):


Answer: Because the hunter will try to aim at the fish, but the image of fish he sees is actually the apparent image of the fish at a location.
Heres an image to help
Hope this helps!
