Question

QUESTION 1

A battery operated car of mass 1,225 kilograms uses a 10.4 volt system. What is the charge in coulombs the batteries must be able to move in order to accelerate the care from rest to 22.7 meters per second? Your final answer must be in scientific notation. Remember that 333 = 3.33e2. All you need to do is give me the number here as I have already given you the units and this silly program cannot handle units.

QUESTION 2

A battery operated car of mass 1,451 kilograms uses a 10.3 volt system. What is the charge in coulombs the batteries must be able to move in order to make the car climb a hill that is 658 meters high? Your final answer must be in scientific notation. Remember that 333 = 3.33e2. All you need to do is give me the number here as I have already given you the units and this silly program cannot handle units.  

QUESTION 3

To travel at a constant speed of 16.6 meters per second on a level road for 2.81 hours,  a car must exert a constant force of 343 newtons to overcome air resistance.   How much charge in coulombs must the 10.9 battery move in order to maintain this force? Remember that power = energy / time and power = force x velocity. One hour = 3600 seconds.
