A 3.00-kg block is placed on top of a 12.0-kg block that rests on a frictionless table. The coefficient of static friction between the two blocks is0.500. What is the maximum horizontal force that can be applied before the 3.00-kg block begins to slip relative to the 12.0-kg block, if the force is applied to each of the following?
(a) Find the acceleration with which Robin is pulled upward.
(b) Find the tension in the rope while Robin escapes.
Homework Answers
Maximum horizontal force= Mg*mu
=3*10*0.5
=15 N
Accelation=
15 N=m*a
15/12=a=1.25 m/s^2
Tension T=Mg+ma
=12*10+3*1..25
=123.75 N
