Homework Statement
:Block B has acceleration of 4 m/s2... Relative acceleration of block A w/ respect to B is 4 m/s2. Find magnitude & direction of accel for A?[/B]
Homework Equations
a_A = a_B + a_A/B[/B]
The Attempt at a Solution
a_A = 4 +4 = 8 m/s2 <
8*cos(20) = 7.52 (xcomponent)
8*sin(20) = 2.74 (ycomponent)
direction= inverse tangent of (2.74 / 7.52) = 20.02 degrees <
this was my attempt, not sure if I did it correctly. [/B]
