Ok thank you I think it's z→z^8

Hi, I need to sketche ach of the following regions: R = {z :|z| < √2, 7π/16 < Argz<9π/16}, R1 = {z :|z| < 16, Rez>0} and write down a one-one conformal mapping f1 from R onto R1. Here is my sketch https://onedrive.live.com/redir?resid=4cdf33ffa97631ef%2110238 But I'm finding hard to find the...

Yes, you are right. I've done the calculations again and the M=5 Also I've done the calculations again for the coordinates and everything looks correct since the coordinates lie within the shape. Thank you for your help.

Ok, I think I did a mistake when I did the calculations. I've done it again and the X-coordinate is 89/16≈5.56

ok, so this is what I did But the result is 303/16≈18.94 and this clearly is not the X-coordinate of the centre of mass. Can anyone help??

An industrial tool is made from alaminar material occupyingthe region between thestraight lines y =2, y=1 2x and y =3−x. The density of thematerial varies and is given by thefunction σ(1 + x), where x is the horizontal distancefrom the y-axis and σ is aconstant. The mass of the...

Yes, all sorted :)

then this is correct PB.Before=m*vb Now I've done part B and the initial velocity after collision is 17.326 So how do I find the total momentum after collision??

it could be, but the diagram is not showing 90 degrees. But if there is no other way of solving this i might do it this way.

If I put PB.Before=m*vb This is why I'm confused, since PA.before has vector components I don't know how to add it up to PB.before to get the momentum after collision.

So, does anyone know the linear momentum for car B??

Well, the question continues as follows, but I only wanted help for part a. (b) The police estimate that the coefficient of friction between the road surface and coalesced cars was 0.9, and that the distance traveled by the coalesced cars was 17m. From these estimates, estimate the speed...

Homework Statement I'm having difficulties trying to figure this out, can you please help? Many thanks. Car A is traveling at a steady speed of 15ms−1 (approximately 32mph) in a straight line when it is hit from the left by car B. Each car has the same mass, and it can be assumed that...

Homework Statement A uniform cylinder of mass m and radius R rests in equilibrium against a rough plane that is inclined at an angle α to the horizontal. The cylinder is supported by a cord under a constant tension, wrapped round it, so that the cord leaves the surface of the cylinder...
