1. The problem statement, all variables and given/known data http://www.webassign.net/CJ/04_11.gif Two forces, F1 and F2, act on the 5.00-kg block shown in the drawing. The magnitudes of the forces are F1 = 30.0 N and F2 = 45.5 N. What is the horizontal acceleration (magnitude and direction) of the block? Direction... Left or Right? 2. Relevant equations F = mass x acceleration acceleration = F / Mass 3. The attempt at a solution I got two x and y components: F1x = cos65 x 30 = 12.68 N F1y = sin65 x 30 = 27.19 N I do not know how to calculate the acceleration, please help and explain. Thanks in advance. *I figured out the horizontal acceleration, but how do you know which direction it goes? Left or right?
