Newton's laws question, me:

when a propagule is ready to fall off of the parent tree, it must overcome the inertia that keeps it in place.

first law of motion

second law of motion

third law of motion

friction

Ais useful when you need a simple machine to you separate two things. a. lever b. screw c. pulley d. wedge

Aperson stands on a platform, initially at rest, that can rotate freely without friction. the moment of inertia of the person plus the platform is ip. the person holds a spinning bicycle wheel with its axis horizontal. the wheel has moment of inertia iw and angular velocity ωw. take the ωw direction counterclockwise when viewed from above. part a what will be the angular velocity ωp of the platform if the person moves the axis of the wheel so that it points vertically upward?

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c
