A 3.28 kg cat is walking on a 4.00 m board (with mass of 8.00 kg) set on two sawhorses. If the center of the board is 0.75 m from one of the sawhorses, how far on the other side of the sawhorse can the cat walk to before the board begins to rotate?

3) A 3.25kg bucket is attached to a disk-shaped pulley of radius 0.184 m and mass 0.823 kg. If the bucket is allowed to fall, what is the angular acceleration of the pulley?

4) A 32.8 kg girl runs with a linear speed of 2.85 m/s on a tangent to a stationary merry-go-round of radius 2.29 m. What is the magnitude of the girl’s angular momentum just before she jumps onto the merry-go-round?

5) What is the power output of a dental drill that operates at 44,900 rpm while producing a torque of 3.75 N-cm? (Give the answer in Watts)
