i thought the max static force was 36.75N as calculated in the above post but then how do i calculate the mass of block c if you do not no the acceleration. sorry i must seem so dumb

thanks for that so the system moves to the right to do part b) is the x component of acceleration equal to (980sin30+490sin53)/150 which equals 5.88 then you do a similar thing for the y component using the cos values then to work out the total acceleration you use Pythagorean therm...

sorry I am not sure then how to correct my error any hints would be greatly appreciated thanks i am so totally confused with this whole topic

Homework Statement Block b with mass 5kg rests on block a with mass 8kg which in turn is on a horizontal tabletop. there is no friction between block a and the table top but the coefficient of static friction between block a and b is 0.75.A light string attached to block a passes over a...
