In a Porter governor, the mass of the central load is 18 kg and the mass of each ball is 2 kg. The top
arms are 250 mm while the bottom arms are each 300 mm long. The friction of the sleeve is 14 N. If
the top arms make 45° with the axis of rotation in the equilibrium position, find the range of speed of
the governor in that position.

QUESTION 14 A chimney (length 18 m, mass 980 kg] cracks at the base and topples.  Assume: - the chimney behaves like a thin rod, and does not break apart as it falls. - only gravity (no friction) acts on the chimney as it falls. - the bottom of the chimney pivots, but does not move. Find the linear speed of the very top of the chimney, in m/s, just as it hits the ground.   QUESTION 15 A 23 kg cart...

A block of mass 2 kg and a block of mass 3 kg are sliding on a frictionless surface. They collide and stick together. Before the collision the first block was travelling at 5 m/s in the positive x direction. After the collision the two blocks are travelling at 6 m/s in the negative x direction. What was the x component of the velocity of the second block before the collision?

Blocks A (mass 2.00 kg ) and B (mass 12.00 kg , to the right of A) move on a frictionless, horizontal surface. Initially, block B is moving to the left at 0.500 m/s and block A is moving to the right at 2.00 m/s. The blocks are equipped with ideal spring bumpers. The collision is headon, so all motion before and after it is along a straight line. Let +x be the direction of the initial motion of A....
