+//to find average power must be applied by the elevator motor
+
+// GIVEN::
+
+//weight of elevator
+w = 5160//in N
+//average weight of passenger
+wp = 710//in N
+//number of passengers
+n = 20
+//distance between floors
+sf = 3.5//in meters
+//time elasped
+t = 18//in seconds
+//acceleration due to gravity
+g = 9.8//in m/s^2
+
+// SOLUTION:
+
+//total weight of elevator and passenger
+//upward force exerted by motor
+F = w+n*wp//in N
+//total height by which elevator moves
+s = sf*25//in meters
+//work done must be applied by the elevator motor
+W = F*s//in J
+//average power
+Pav = (W/t)*10^-3//in kW
+
+//value of force F is slightly different than scilab answer
+//but silab answer is same as calculator answer
+printf ("\n\n Upward force exerted by motor F = \n\n %5i N",F);
+printf ("\n\n Work done must be applied by the elevator motor W = \n\n %.1e J",W);
+printf ("\n\n Average power Pav = \n\n %2i kW",Pav);
