Answer:
L = mp*v₀*(ms*D) / (ms + mp)
Explanation:
Given info
ms = mass of the hockey stick
uis = 0 (initial speed of the hockey stick before the collision)
xis = D (initial position of center of mass of the hockey stick before the collision)
mp = mass of the puck
uip = v₀ (initial speed of the puck before the collision)
xip = 0 (initial position of center of mass of the puck before the collision)
If we apply
Ycm = (ms*xis + mp*xip) / (ms + mp)
⇒ Ycm = (ms*D + mp*0) / (ms + mp)
⇒ Ycm = (ms*D) / (ms + mp)
Now, we can apply the equation
L = m*v*R
where m = mp
v = v₀
R = Ycm
then we have
L = mp*v₀*(ms*D) / (ms + mp)

Answer:
<h2>
<u>76.36m/s</u></h2>
Explanation:
Step one:
given data
let the mass of the rider be m,=110kg
let the velocity be v=?
let the mass of the car be M,=110kg
let velocity of the car V=6m/s
Step two:
the momentum of an object is given by the expression
P=mv
<em />
Step two:
<em>since the two the bicycle rider must have the same momentum as the car,</em>
<em>then we need to equate their momentum</em>
mv=MV
110*v=1400*6
110v=8400
divide both sides by 110 to find v
v=8400/110
v=76.36m/s
<u>The rider is expected to have a speed of 76.36m/s</u>
Answer:
B.
Explanation:
The water collects in the ocean; it is then evaporated by the sun. After evaporation the water turns into water vapor, it then condenses to form clouds.
