Oh, yes. I am sorry. I am attempting to calculate the height of the fountain. It does indeed seem rather high. But the numbers for my assignment are randomly generated. So that may explain this phenomenon. Thank you for your help.

So, the question is stating that the time period you are looking for is when the ball is thrown at 1 second and goes to .1 second. So, you want the velocity of the ball at the interval [1,1.1]. Velocity is the change in distance/ change in time. What is t...

I tried that and did not get the right answer. I think I need to use KE_i + PE_i = KE_f + PE_f ... which would be: .5mv_i^2 + 1/2Iw_i^2 + mgh_i = 1/2mv_f^2 + .5Iw_f^2 +mgh_f --> I= 2/5mr^2 for a solid sphere I factored out the mass on both sides but my pr...

So the answer for "Give the equation of the line in rectangular coordinates." is sqrt(x^2+y^2) = 4 [sqrt(x^2+y^2) ]/y? Or is it the y=4? Again, that's probably a silly question..

Because diameter is twice the radius, the radius must be 1/2 of 8 ft. So r=4ft. The circumference is equal to 2*pi*radius. Since pi is =3.14 Thus by comparing the two equations D=2r C=2rpi the only difference is pi so the answer would be F if you assume 3...
