Acar rolls along a surface with a coefficient of friction of .795 i f the car has a mass of 905 kg, what force is needed to accelerate the car from rest to 102.5 km/hr in 10 sec?

According to the law of conservation of mass, in a chemical reaction the total starting mass of all the reactants equal the total final mass of all the products. true or false?
