Homework Statement A solid cylinder with a mass of 1.12 kg and a radius of 0.017 m starts from rest at a height of 3.40 m and rolls down a 77.7◦ slope. What is the translational speed of the cylin- der when it leaves the incline? The acceleration of gravity is 9.81 m/s2 . Answer in units of...

anyone? I have no clue how to find the velocity at either checkpoints with the given data

how would you go by doing that?

yea my browser won't load the functions so it should read V(sub)B which is the velocity once it reaches checkpoint B.

Homework Statement Part 1 Consider a car which is traveling along a straight road with constant acceleration a. There are two checkpoints, A and B , which are a distance 81.4 m apart. The time it takes for the car to travel from A to B is 5.89 s. Part 2 Find the velocity VB for the case where...

Homework Statement An = {(1+3/n)^(4n)} The Attempt at a Solution Used the root test but it led to an inconclusive solution

I put this in the homework section a few days ago, but the homework was already due, and I'd like an explanation as to how to do this please. I have a feeling a similar problem will be on the exam. The widths (in meters) of a kidney-shaped swimming pool were measured at 2 meter intervals as...

anyone have suggestions?

i did this, but the answer is not working...i'm getting (b-a)/6 is 4/6 any other suggestions to this because I am having trouble. thanks I don't think it makes a difference but the answer is asked for in meters squared

Homework Statement The widths (in meters) of a kidney-shaped swimming pool were measured at 2 meter intervals as indicated in the figure. Use Simpson's Rule to estimate the area of the pool. Please round the answer to the nearest square meter. a = 5.8 b = 6.6 c = 5.4 d = 5.8 e =...

The original function x^2+x can be seen as x^2+x^1 n is the exponent for each x, so for the first x, n=2 and n=1 for the second x then use the derivative formula which is dy/dk of f(x) = nx^(n-1) which would mean the derivative is 2x^(2-1)+1x^(1-1) which equates to 2x^2+1 since it asks what...

thanks again I appreciate it

Can anyone help me as to where to start this one out? Thanks \int(1+\sqrt{x})^8 dx

ahhh yes i see it now. Thanks a bunch.

Thanks with the hint on u substitution, that was a lot easier Another question if possible. How would you start the integral \int\frac{earctany)}{1+y^2} with boundries of -1 to 1 I can't seem to find the trick...
