Here is a picture of the problem. The question is: A force F0 causes an acceleration of 17 m/s2 when it acts on an object of mass m sliding on a frictionless surface. Find the magnitude of the acceleration of the same object in the circumstances shown in each figure below. Figure (a) m/s2 Figure (b) m/s2 My problem is Im not too sure what the problem wants me to do. It gives me the acc. of 17 m/s^2 but how come it asks me to find the magnitude of the acc.? Can somone please rephrase this into simpler terms? I want to do this on my own but Im just confuse on what this problem want me to do. Any help would be appreciated.
