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
