    1. The problem statement, all variables and given/known data

    1a) Find the work done by the force of gravity.
    Given- Force = 350 newtons
    distance = 2.00
    1b) find the power of a lawn mower the time is 30 min and the force is 88 newtons and the distance is 1.2 km

    2a) a 15 kg cart starts from rest, travels 10 meters with a force of 105 newtons. what is the final velocity?

    2b) What is the carts work while pushing down the aisle
    2c) what is the carts final kinetic energy?

    2. Relevant equations

    P= w/t , KE= 1/2mv^2, w=Fdcos(beta)

    3. The attempt at a solution
