A rubber ball weighs 49 N. What is the acceleration of the ball if an upward force of 69 N is
applied?

  • maths/physics -

    Hint: The net force on the ball is
    F = 69 - 49 = 20 N

    The mass of the ball is
    M = 49/g = 5.0 kg

    The acceleration is a = F/M

  • maths/physics -

    4 meters / (seconds squared)

  • maths/physics -

    13.8
