    1. The problem statement, all variables and given/known data
    1. What is the kinetic energy in joules of a 950-lb motorcycle moving at 50 mph ?

    2. If the speed of the motorcycle changes from 50 mph (with kintic energy K1) to 25 mph (with kinetic energy K2), what is the ratio of K1 to K2?


    2. Relevant equations

    KE=1/2mv2


    3. The attempt at a solution
    1. 1.1×10 5 J
    2. k1/k2= 0.25

    Re: Thermochemistry

    You already posted this in the homework section, this area isn't for homework problems, and this problem has nothing to do with chemistry.

    You hit the trifecta.
