W=F x S
W=900 x 10m
so work done is 9000 joules
power= work/time
9000 / 30
power is 300 watt
W=900 x 10m
so work done is 9000 joules
power= work/time
9000 / 30
power is 300 watt

Your answer is :--
Given, force f = 900N
distance d = 10m
time taken t = 30s
•°• work done W = fd
=> W = 900×10
=> W = 9000joule
power p = work/time
=> p = 9000/30
=> p = 300watt
