2m/s^2 how to get it: since you already know the force and mass and the formula for force is force=(mass)(acceleration) you isolate the variable of acceleration which is a by dividing (m)(a) by (m) which equals f/m=a then you plug in your known numbers where they go so f=100N m=50kg 100N/50kg= 2 therefore the acceleration is 2m/s^2 hope this helped you!!!
