Answer:
Work done by battery will be equal to 10.238 J
Explanation:
We have given ideal an ideal battery with ideal voltage V = 24 volt
Constant current
Resistance will be equal to
Time is given t = 3 minutes = 3×60 = 180 sec
We have to find work done by battery
Work done is equal to
So work done by battery will be equal to 10.238 J
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)
You would multiply the 2 and the 103 together to have one number to work with rather than one equation to make up another equation. You would do the same with 1.2 and 103. Multiply the results with their velocity (206 and 123.6), like so. 206*14 and 123.6*21. From this, you would get 2884 and 2595.6. Add them together and divide that answer by three. The answer should be 2739.8.
Hope this helps!
