A block and sphere are connected by a cord that passes over a pulley as shown. Neglect friction and assume the cord is massless. Take 
m1 = 2.00 kg,
 
m2 = 4.50 kg,
 and 
𝜃 = 50.5°.

A triangular structure is oriented such that its base rests upon a horizontal surface, its left side is perpendicular to its base, and its right side forms an incline of angle 𝜃. A pulley is attached to the structure's apex. Two objects are connected by a cord that passes over the pulley.
A circular object labeled m1 is attached to the to the left end of the cord and hangs freely.
A rectangular object labeled m2 is attached to the end of the cord and rests upon the incline.

What are the magnitude of acceleration (in m/s2) of the block and sphere?
