Power = Work/ time......(1)
Work = Force*distance.....(2)

(1) => power = Force*speed
power= (1000+10000) *.5 = 5.5 kW

You need to add the 1000 N force required to overcome resistive forces.

At the exam do we get a formula sheet for AS physics?
I don't know that that's why I asked.

You get a formula sheet, but it doesnt have all formulas. You can check it, its is on the second and third page of each past paper
