How Does Tilting Affect the Height of Point P Above the Floor?

[chris99191]

1. A rectangle crate has height, h, which is half the length 2h. O is the bottom left corner and P is the top right. When a line is drawn through O to P it makes the angle a. When the crate is tilted on O it makes angle b with the ground. Show that the height of P above floor after being tilted is h(cosb+2sinb)


2. h(cosb+2sinb)


3. I have noo idea where to even start

With what? The horzontal- i.e. ground?

When the crate is tilted on O it makes angle b with the ground.

Does "it" still refre to ine OP?

It would be instructive for you and us if you made a drawing of the problem...
