## 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?

## Homework Equations

a_A = a_B + a_A/B

x_A = x_B + x_A/B

y_A = y_B + y_A/B

## The Attempt at a Solution

x & y components:

-4cos(20) = -3.76

-4sin(20) = -1.37

-3.76 = 4 + x_A/B

x_A/B = -7.76

y_A/B = -1.37

|a| = sqrt( -7.76^2 + -1.37^2 ) = 7.88 m/s2

direction: tan -1 * (-1.37/-7.88) = 10.01 degrees
