Question1
A 408 kg mass is brought close to a second mass of 110 kg on a frictional surface with coefficient of friction 1.2.
At what distance will the second mass be- gin to slide toward the first mass? The acceleration of gravity is 9.8 m/s2 and the value of the universal gravitational constant is 6.67259 × 10-11 N • m2/kg2.Answer in units of mm
Question2
One end of a uniform meter stick is placed against a vertical wall. The other end is held by a lightweight cord that makes an angle with the stick. The coefficient of static friction between an end of meter stick and wall is 0.37. Let an angle between cord and stick is theta = 18. A block of the identical weight as the meter stick is suspended from the stick, at a distance from the wall. What is the least value of for which stick will remain in equilibrium?
