two blocks are connected by an ideal string which passes over an ideal pulley which is massless anf frictionless. the inclination of the ramp is theta $=43\mathrm{.}7$ while the masses m$1=7\mathrm{.}7$ kg and m$2=15\mathrm{.}9$kg$.$ friction is negligible. what is an expression for the magnitude of acceleration for the two blocks. give the equation in terms of the variable a$,$ and use g for the acceleration due to gravity. assume the block $2$ descends vertically
