In my working i have;
For a)
##\tan 55^{\circ} = \dfrac{450}{R}##
##R = \dfrac{450}{\tan 55^{\circ} }= 315 N##
part b) no problem here ...horizontal to left.
c) This is where my real doubt is,
i have using sine rule;
##\dfrac{9.8}{sin 55^{\circ} }= \dfrac{a}{sin 35^{\circ}}##
##a = \dfrac{9.81 \sin 35^{\circ}}{\sin 55^{\circ}} = 6.86 ## m/s
There could be an alternative approach.
