A lightweight electric car is powered by a series combination of ten 12.0-V batteries, each having negligible internal resistance. Each battery can deliver a charge of 154 A · h before needing to be recharged. At a speed of 82 km/h, the average frictional force due to air drag and rolling friction is 1.34 kN. (a) What must be the minimum power delivered by the electric motor if the car is to travel at a speed of 82 km/h? ________kW...
A pure electric car is designed to operate with 12 V battery with a total energy of 2.00×10^7 J stored when it is full. When the car moves with constant speed of 20.0 m/s, its electric motor spends 8.00 kW power. a) Find the current used by motor. b) Determine the distance you can travel with one charge.
3. A pure electric car is designed to operate with 12 V battery with a total energy of 2.00010? 5 stored when it is full. When the car moves with constant speed of 20.0 m/s lits electric motor spends 8.00 kw power. a) Find the current used b) Determine the distance you can travel with one charge distance by motor
3. A pure eletric car is designed to operate with 12 V battery with a total energy of 2.000107 stored when it is full.

2. Suppose a car travels 108 km at a speed of 20.0 m/s, and uses 2.20 gallons of gasoline. Only 30% of the gasoline goes into useful work by the force that keeps the car moving at constant speed despite friction. (The energy content of gasoline is 1.3 ✕ 108 J per gallon.) (a) What is the force exerted to keep the car moving at constant speed? N (b) If the required force is directly proportional to speed, how many...
