A subwoofer needs a household voltage of 110 V to push a current of 5.5 A through its coil. What is the resistance of the subwoofer?
R = V ÷ I = 110V ÷ 5.5A = 20Ω
A car starts from a stoplight and is traveling with a velocity of 10 m/sec east in 20 seconds. What is the acceleration of the car?
Solving the problem gives an acceleration value of 0.5 m/sec2.
