Homework Statement
The ceiling-mounted bicycle rack (shown in "Capture" image in attachments) with dimensions p = 50 mm, q = 1000 mm and r = 150 mm for a bicycle that weighs F = 200 N.
The rack is to be made from two parts, ABC and BD, cut from a steel tube and then welded together at B...
Homework Statement
If x = (x1, x2) and y = (y1, y2)....
Show that <x,y> = 3(x1)(y1) - (x1)(y2) - (x2)(y1) + 3(x2)(y2)
Homework Equations
I know that to define it as an inner product space, the following must be correct:
<x,y> = <y,x>
a<x,y> = <ax,y>
<x,y+z> = <x,y> + <x,z>...
Homework Statement
I have 2 bases, a = {1, x, x^2} and b = {-2 - 2x + 3x^2 , 1 + 2x - x^2 , -1 - x + 2x^2} of P2.
Find the transition matrix Pab.
How is this done?!?!
Homework Equations
Since this is Linear Algebra, there aren't really any relevant "Equations" as such. More logic...

Homework Statement
A ball of mass 0.9kg is shot from a slingshot at an angle of 60° from the ground. The slingshot is sitting 1m above the ground. The elasticity of the slingshot is k = 700N/m. Take gravity = 10m/s^2
Air resistance must be taken into account also. Use the formula D = (...
