    Physics questions

    An astronaut on a strange planet has a mass of 80 kg and a weight of 240 N. What is the value of the acceleration due to gravity on this planet?

    F = ma

    240 = 80 x a
    80 80

    A= 3 m/s^2

    Next one question

    What is the mass of a cart that has an acceleration of 4 m/s^2 when a net force of 2000 N is applied to it?

    F = ma

    2000=m(4)


    2000 = 4m
    4 4

    m= 500kg





    Did these need to know if this right or wrong?
