B Computing force given mass and distance

  1. Sep 20, 2016 #1
    if you have an object weighing 50kgs, and you have to move it forward with a distance of 500m, no time given, what force do you need?

    Force is equal to the product of mass and
    acceleration?
    acceleration is not given.

    Sliding over ground? Floating on water? Floating in space?

    Yes., sliding on the ground.

    Look up static and kinetic friction.

    okay. I'm on it.
    Thank you!

    Yes if it is sliding on the ground and you know the coefficient of friction then you will be able to calculate the acceleration of the object from applying a given force

    There is no unique answer. To move the object, you can use any force that overcomes the static friction force. Larger forces will move it the required distance in shorter times.
