two forces act on a moving object with a mass of 27kg.one force has a magnitude of 12N and points south, while the other has a magnitude of 17N and points due west. Whats the acceleration of the object?

physics 
venkat,
The magnitude of the net force is
F =sqrt[(12N)^2+ (17N)^2]
= 20.80N
The acceleration of the object is
a = F/m
Here m = 27 kg
Substitute the values for a.
