1. i asked to make gravity drive ( vehicle powered by potential energy, which is to travel in an
approximately as far as possible). And i need to make the report. But there is part that i cant
understand. can someone help me to explain, about analysis of the possible motion of that
vehicle ( car) ? thank you :)
Solution
To be driven by potential energy, the car must move downwards by some distance
Consider the bottom half of a circle. If the car starts from Rest at one end, It gains v=(2gR) 1/2
at
the bottom of the semi-circle.which is used to move to the other end.So, The car has moved a
distance of 2R using potential energy .
So, basically the car must go from high to low height in order to drive using potential
energy.There must be a part where the car goes to lower height than it initially started with
