A roller coaster engineer designed the first drop to have a gravitational potential energy of 100,000 joules , he knows that 10% of that energy will be lost of friction (thermal energy ) to make it up to the next hill , the very will take 80,000 joules of kinetic energy . Will the cart make it up to the second hill ?... claim the answer use math and definitions physical laws !
