1. The magnitude of the vectors F is 18 N, the force on the right is applied at an angle 63◦ and the the mass of the block is 35 kg. If the surface is frictionless, what is the magnitude of the resulting acceleration? 2. Relevant equations F=ma 3. The attempt at a solution so they are asking me for resultant acceleration, this tells me that i have to treat this as a vector problem right? then: Fx= 18N Fy=m*a*cosθ a=sqrt(ax^2 +ay^2) am I right?
