[QUOTE="HallsofIvy, post: 5223418, member: 637751"] Since the mass of the crate is 55.0 kg and g= 9.81, the [b]weight[/b] of the crate is 55.0*9.81= 539.55 Newtons. Multiply that by the given coefficient of friction, 0.350, to get the friction force, 188.8425, or to three significant figures, 189 Newtons. Subtract that from the applied force (assuming it is horizontal) to get the net force acting on the crate. Then use "F= ma" to find the acceleration. [/QUOTE]
