first find the resultant force....

In vector form total force on mass is : (27.5 i + 13j) N

         F = (202+152+2.20.15.cos60 )1/2 = 5(37)1/2 N

       As   F = ma

accln. = a = 6.083 m/sec2

we'll get accln, and for direction of accln,  the direction of resultant force will be same as of accln.

so direction is d = tan-1(13/27.5)

 direction of accln. = 25.3 degrees with F1
