**Henry**, Thursday, December 6, 2012 at 8:09pma. Fc=m*g = 35kg * 9.8 N/kg = 343 N @ 0o

= Force of crate.

Fp = 343*sin(0) = 0 = Force parallel to

floor.

Fv = 343*cos(0) = 343 N. = Force perpendicular to floor.

Fk = u*Fv = 0.3*343 = 103 N. = Force of

kinetic friction.

Fn = Fx-Fp-Fk = ma.

Fx - 0 - 103 = m*0 = 0

Fx = 103 N. = Hor. force applied.

b. Fx - Fp = 0

Fx - 0 = 0

Fx = 0.
