Question

A block of mass 10kg is sliding on a surface inclined at an angle of 30°with the horizontal. if The coefficient of friction btween the block and the surface is 0.5 . Find the acceleration produced in the block

Answer 1

F=ma

F=kmg

then ma=mg sin - kmg cos

a=10*1/2-0.5*10*1.732/2

a=5-4=3301

a=0.6699
