acceleration = (force)/(mass) \\

1) We have :


a = (50)/(8) = (25)/(4) = (12.5)/(2) = 6.25 \\

2) We have :


a = (60)/(9) = (20)/(3) = 6.67 \\

_________________________________

3) We have :


a = (24)/(4) = (12)/(2) = 6 \\

_________________________________

4) We have :


a = (75)/(12) = (25)/(4) = (12.5)/(2) = 6.25 \\
