[QUOTE="jpsmith394, post: 4519370, member: 489461"] [h2]Homework Statement [/h2] The horizontal surface on which the block slides is frictionless. If F = 20 N and M = 5.0 kg, what is the magnitude of the resulting acceleration of the block? The force is applied 30° to the horizontal. [h2]Homework Equations[/h2] [itex]F=ma[/itex] [h2]The Attempt at a Solution[/h2] I began by ignoring the weight and normal force in the vertical axis (y-axis) because the surface is frictionless. Then my next step is to separate the force into compenets with [itex]F_{x}=Fcos\theta[/itex] Therefore: [itex]ƩF_{x}=Fcos\theta = ma_{x}[/itex] So: [itex]a_{x}=\frac{Fcos\theta}{m}[/itex] And using the given numbers I got a solution of 3.46[itex]\frac{m}{s^2}[/itex] But the online system I am using shows the correct answer as 7.5[itex]\frac{m}{s^2}[/itex] [/QUOTE]
