    math challenge!!!

    Where (mo) is the rest mass, thus the relativistic kinetic energy is: T= mc^2 - (mo)c^2 Find the relativistic kinetic energy of a proton (mo= 1.67x 10^-27kg) moving at 0.9 c and compare this to the value obtained from the classical formula (Ek= 1/2 mv^2) :haha: Goodluck guys

    HELP!!!! im sooo confused??

    An apollo launch vechicle has a total mass of 3.4x10^6kg at lift off. The first stage contains 2.0x10^6kg of propellants (fuel and oxygen) which is consumed at a rate of 1.4x10^4kg s a) find the minimum thrust of the engines at lift off b) if that thrust (from a ) is sustained, find the time...
