Asolar car undertakes a straight 3000km from south to north • the trips duration is 31 days in the month of july • the total solar cell surface area of the vehicle is perfectly horizontal at all times the maximum speed of the car is achieved when the maximum power is delivered by the solar cells. the speed can be assumed to increase linearly from oms-1 at ow power to the maximum point. you can ignore all aerodynamic aspects of the vehicle, i. e. the speed of the vehicle is only affected by the power delivered. you are allowed to take some average values, however, this has to be justified and reasonable. for example, you might use latitude values averaged every 200km after calculating that the effect of latitude on your calculation is minimal over this distance. part (a) –.. assuming you travel at a constant speed of 60 km hr-, how many days will your journey take? the answer should include the number of full days, plus the number of hours on the last day. for this question you can assume that if the sun is shining the car is moving at 60kmhr! part (b) in part (a) we assumed a constant speed throughout the day. now we want to investigate this in a bit more detail. for the first and last full day of travel, calculate the velocity distributions over the course of each day, and the average velocity for each day. how does this compare to the 60 km hr"'? what is the distance travelled on each day?
