Question

How much force is needed to accelerate a 68 kilogram-skier at a rate of 1.2 m/sec^2?

1 Answer

  • The sum of forces = mass x acceleration

    Ignoring all resisting forces like friction and air resistance, the only force is gonna be the one pushing the skier

    So, 
    Force = mass x acceleration

    Now, we substitute the values given

    Force = 68 x 1.2

    And therefore, Force = 81.6 N
