Answer:

P = 0.98 W

Step-by-step explanation:

Given that,

Mass, m = 1 kg

Height, h = 0.9 m

(a) We need to find power must the battery supply to the vehicle for a run time of 9 seconds. Power is given by work done divided by time. It can be given by :


P=(W)/(t)\\\\P=(mgh)/(t)\\\\P=(1* 9.8* 0.9)/(9)\\\\P=0.98\ W

So, the required power is 0.98 W.
