Can someone please tell me what I am doing wrong? Thank you!

(3) Find the useful power output [in W) of an elevator motor that lifts a 2800 kg load a height of 35.0 min 12.0 5, if it also inneaeee the speed from rest to 4.00 m/s. Note that the total mass of the counterbalanced system is 10,000 kgiso that only 2800 kg is raised in height, but the full 10,000 kg is accelerated. (Enter a number.) 3433500 x W (b) What does it cost (in cents), if electricity is $00900 per kW - h? (Enter a number.) 2635 X cents
