Question

What is the power required to raise a 1.81x10^4 newton elevator 12.0 meters in 22.5 seconds?

a) 8.04x10^2 W
b) 9.65x10^3 W
c) 2.17x10^5W
d) 4.89x10^6W

Answer 1

Answer:9.65×10^3w

Step-by-step explanation:

Force=1.81×10^4newton, distance=12meters, time=2.25seconds

Power=work/time=(force×distance)/time=(1.81×10^4×12)/2.25=9.65×10^3w
