Question

9. An ox can apply a maximum force of 1000 N. It is
taking part in a cart race and is able to pull the cart
at a constant speed of 30 m s-1 while making its best
effort. Calculate the power developed by the ox.​

Answer 1

Answer:

Correct option is

B

30kW

Power=work/time

Work=F×S

Power=F×S/t

Power=F×v, where v is the velocity as it is rate of change of displacement.

P=1000×30=30kW.
