Hi, Im having a little problem doing a question in mastering physics, I was wondering if anyone can help. here is the problem: A finite rod of length L has total charge q, distributed uniformly along its length. The rod lies on the x -axis and is centered at the origin. Thus one endpoint is...

A small circular hole 6.00 mm in diameter is cut in the side of a large water tank, 14.0 m below the water level in the tank. The top of the tank is open to the air. A) What is the speed of efflux? sqrt(2*g*h) = 16.6 m/s B) What is the volume discharged per unit time. This is...

Thanks alot, I appreciate the help.

-DE^2sin(Et)?

This is what I get, 12At^2 + 6Bt + 2C - DEsin(Et) is this correct?

If is the answer for the instantaneous velocity, what is the difference between that and instantaneous acceleration.

T-m1gsin(theta) = m1a -t+m2g=m2a -(m1gsin(theta)+m1a)+m2g=m2a the I got the acceleration a= m2g-m1gsin(theta)/m1+m2 T=m1gsin(theta)+m1a this what I used to get T, my teacher had showed us a similar problem..

would the instantaneous velocity and acceleration be different in this question.

Hi, Im still having problems solving part a, but I did part b, and I got T=39.19.

if I replace D, E with X, can I do that? then I would get xsin(xt)=sin(Xt)cos(Xt)?

Sin(Et)+Dcos(Et)? something like this, Ill go back and read my Calculus book.

yeah I did in Cal1, but haven't touched it in a while

for t i get 6.59

would it be sin(Et) only..

Thanks Nate, I appreciate the help.
