Question 1162033
<font face="Times New Roman" size="+2">


Hint:  Since Force equals mass times acceleration, if acceleration is zero, net force must be zero.  Hence, the applied force and the friction force must be equal when the applied force is 8.4 N.  Then then net force when the applied force is 10.92 N, must be 2.52 N.
