Sagot :
5789.8 W is the average power of the elevator motor during this period and 1.115 * 10⁴ W this power compare with the motor power when the elevator moves at its cruising speed.
What is an explain acceleration?
The rate with which the speed and direction of a moving object vary over time. A point a object going straight ahead is pushed when it accelerates or decelerates.
Briefing:
Mass of elevator = 650 kg
Time = 4.50 sec
Speed of the elevator = 1.75 m/s
Calculating the elevator's acceleration is necessary.
Using the acceleration formula
a = vf - vi / t
a = 1.75 / 4.50
a = 0.38 m/s2
(a). We must determine the net force acting on the elevator.
Using the force formula
T = mg + ma
T = m (g +a)
T = 650 (9.8 + 0.38)
T = 6617 N
We must determine the average velocity.
Using the average velocity formula
v' = vf + vi / 2
v' = 1.75 / 2
v' = 0.875 m/s
We must determine the average power.
Using the power formula
P = T * v'
P = 6617 * 0.875
P = 5789.8 W
(b). We must determine the motor's power input.
Using the power formula
P = F * v
P = mg * v
P = 650 * 9.8 * 1.75
P = 1.115 * 10⁴ W.
