(a) What is the acceleration of the object if a 335 N horizontal force is applied to the box?

m/s2

(b) What is the acceleration if the applied force is 465 N

**drwls**, Tuesday, December 18, 2012 at 10:42pm(a) It takes a force of 0.64 M g = 314 N to make it move, so it will move in this case. The kinetic friction force opposing motion will be

0.17 M g = 83 N. The net applied force is

Fnet = 335 - 83 = 252 N

Acceleration = Fnet/M = 5.04 m/s^2

(b) The method of solution is the same.
