Problem

An electric scooter of total mass 75 kg75\,\text{kg} experiences a constant resistive force of 200 N200\,\text{N} while moving on a level road. The scooter’s motor can deliver a continuous power of 600 W600\,\text{W}. a. (i) Calculate the maximum constant speed the scooter can maintain. Give your answer in m s−1\text{m\,s}^{-1}. b. (ii) Express this speed in km h−1\text{km\,h}^{-1} to the nearest whole number.
