The coefficient of static friction between 3.00 kg crate and the 35.0 incline is 0.300.what minimum force F must be applied to the crate perpendicular to the incline to prevent the crate from sliding down the incline

Answer 1

force of gravity along the incline is
... m g sin(35º)

force of gravity perpendicular to the incline
... m g cos(35º)

.300 {x + [m g cos(35º)]} = m g sin(35º)
