An important difference between a universal and a split-phase motor is that the split-phase motor has a. two brushes attached to the stator. b. a single coil formed on the rotor. c. two windings on the stator. d. an armature with a commutator.

An important difference between a universal and a split-phase motor is that the split-phase motor has

A. two brushes attached to the stator.

B. a single coil formed on the rotor.

C. two windings on the stator.

D. an armature with a commutator.

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
