Finding acceleration of an object given force and mass?

  1. Apr 26, 2016 #1
    1. The problem statement, all variables and given/known data
    Snooker ball with mass 100g is struck by a billiard cue. Cue imparts a force of 20N to the ball and the duration of the impact is 0.01s.

    2. Relevant equations
    F=ma

    3. The attempt at a solution
    F=ma
    20=1(a) *I converted 100g to 1kg*
    a= 20ms(^-2)

    The answers claim that the acceleration is 200ms^-2. Except, I do not know how they have come to this, and which conversions I got wrong. I also left 100g in grams, but still did not result in the given answer.

    Thank you if you can help me :-)

    To convert from grams to kilograms, you need to divide the mass in grams by 1000.
