 Posted: Sun Mar 20, 2011 9:26 pm    Post subject: The momentum of an object is given by it mass x velocity. http://www.splung.com/content/sid/2/page/momentum You can work out the velocity of the bus by equating the mass of the bus x its unknown velocity with the mass of the trolley x velocity of the trolley. Solve for the velocity of the bus. You can work it out the numbers.
