Question

(c4p46) A 5.6- kg concrete block rests on a level table. A 3.6- kg mass is attached to the block by a string passing over a light, frictionless pulley. If the acceleration of the block is measured to be 1.2 m/s2, what is the coefficient of friction between the block and the table?

Explanation / Answer

3.6 *9.8 - T =3.6*a

T - u*5.6*9.8 = 5.6*a
a=1.2
T = 30.96
u = 0.44
