i know:
force perpendicular (y) is the force applied*the sin of theta
force parallel (x) is the force applied*the cos of theta
the force due to gravity is the mass*gravity
Fn+Fp-Fg= 0 because the crate is not floating
Fn=-Fp+Fg
Fk=coefficient of friction*Fn
Force perpendicular-Fk=m(a of...
:cry: some other problems if anyone has any ideas
1. the coefficient of static friction between the 3.00 kg crate and the 35 degree incline is .300. What is the magnitude of the minimum force, F, that must be applied to the crate perpendicular to the incline to prevent the crate from sliding...
ok so i got that the force perpendicular (x) - (subtract) the force of friction = mass*acceleration of x
but the question does not give you a mass!
how do i determine the normal force if i don't have a mass?
Coefficient of kinetic friction
:confused: so I am working on the force of friction and overcoming friction
i know that the coeffcient of friction is equal to the kinetic force over the normal force and i can get these when hte system is on a horisantal surface
But i don't understand how to...
