A person moves a full sam's club shopping cart mass=80.0 kg from rest

  1. Mar 21, 2012 #1
    a person moves a full sam's club shopping cart mass=80.0 kg from rest to a velocity of 1.30 m/s over a distance of 1.80 meters to secure a spot in check out line.

    A. find the time required to get the cart moving from rest to 1.30 m/s?

    B. Determine the change in the chart's momentum?

    c. determine the magnitude of the force exerted on the cart by the person.

    D. the result from part c ignores friction. if the shopping cart's coefficient of friction is .40 determine the force required by the person to move the cart. (recall the friction force = UFn)
