the force is located on the center of mass of the rectangle, the pivot point is the bottom corner that is lowest on the ramp. i just don't know how to put it all together.

A uniform 10 cm x 20 cm box is placed on a ramp that rises at angle theta above the horizontal. Assuming that there is enough friction to prevent this box from sliding, what is the largest that theta can be without tipping it over? do i use torque = r*F*sin*(theta), if so how do i use it?

thank you

Homework Statement A block of mass M rests on a frictionless horizontal surface and is attached to a wall by a spring of spring constant k. A blob of putty of mass m and horizontal speed v collides with and sticks to the block. Find the maximum compression of the spring. can anyone help?
