Question

A 12 kg block rests on a 4 kg bracket shown

in the ?gure. The 4 kg bracket sits on a

frictionless surface. The coe?cients of static

and kinetic friction between the 12 kg block

and the bracket on which it rests are 0.5 and

0.3, respectively.

A 12 kg block rests on a 4 kg bracket shown n the figure. The 4 kg bracket sits on a frictionless surface. The coefficients of static and kinetic friction between the 12 kg block and the bracket on which it rests are 0.5 and 0.3, respectively. What is the maximum acceleration of the bracket if the 12 kg block is not to slide on the bracket? What is the corresponding force applied?

Explanation / Answer

F = 0.5*12*9.8 = 58.8N

a = 58.8/16 = 3.675m/s^2
