Question

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 = 7.65 kg,

and

? = 49.0°.

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 ?. 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.

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

_____m/s²

(b) What is the tension (in N) in the cord? (Enter the magnitude.)

____N

____m/s

(d)What If? If the incline under m₂ is rough, what is the minimum value of the coefficient of static friction

?_sfor which the system will not move?
