Asked by Ana

A 2.0 kg mass is sliding on a flat surface, with an initial speed of 20 m/s, and a coefficient of friction of 0.2. what is the magnitude of its acceleration? I know the answer is 2.0 m/s^2, but can someone show me how ?

a=force/mass=.2*mg/m=.2*9.8=you do it. I hope your teacher is not using for g 10.0 (no where on the Earth is it that value).
