Can anybody help me w/ this question??

A flight attendant pulls her 70.0 N flight bag a distance of 252 m along a level airport floor at a constant speed. The force she exerts is 44.0 N at an angle of 52.0° above the horizontal.

(a) Find the work she does on the flight bag.

(b) Find the work done by the force of friction on the flight bag.

(c) Find the coefficient of kinetic friction between the flight bag and the floor.

a) What I did was w=F*d*cos(angle) which would mean

w=44*252*(cos52)

w=-1807.241777 J

But it's on webassign and it told me that was incorrect...

Can someone tell me what I'm doing wrong??

b)I was kind of clueless on this one, but what I did was

Ffric=(mew)(m)(g)(cos.angle)=Work done for part a??

but since I dont have part A i couldnt finish this one or Part c....
