Question
1) An elevator motor moves a car with six people upward at a constant speed of 2.10 m/s. The mass of the elevator is 6.00 102 kg, and the average mass of a person on the elevator is about 84.0 kg. Calculate the electric power that must be delivered to lift the elevator car, assuming half of the necessary power delivered goes into thermal energy.
______W
2) (I submitted this question previously and it was answered incorrectly, so if you could help with this one as well that would be greatly appreciated!)
An object is subject to a force
such that 10,050 J of work is performed on the object. If the object travels 29.6 m in the positive x direction while this work is performed, what must be the displacement of the object in the y direction?
_______m
Explanation / Answer
Multiple questions Allowed to answer only 1 question at a time According to the chegg guidelines.
1) mass = 6.00 102 kg s = 2.10 m/s M = 84.0 kg Mass ( T) = 6 people * 84.0 kg + 600 kg = 1104.0 kg
Now we solve for the value of power = 1104.0 kg * 9.8 * 2.10 m/s = 2.272032 * 10 ^4 Watt *2 = 45.44064 kW OR 45440.64 Watt ==ANSWER)
