me too not good in drawing.. i can only sing and back to work silver haha

cybershadow · Answer

N = (m+M)gcos60
force of friction = f = 0.3N
ma = f - (m+M)gsin60

anonymous · Answer

|dw:1389279407506:dw|
f=uxmgcos60    (u=coefficient of friction)
N=mgx cos60    (frictional force=u xN  ---->originally)

equation parallel to the plane---->  mgsin60-f=mxa (acceleration of man and sleigh)
equation perpendicular to the plane ----> N=mgxcos60
