IT IS NOT A.IF YOU ANSWER A, YOU WILL GIVE ME 20 POINTS!!!!!!!!!

Answer 1

Good morning mate...

Force=mass time acceleration newton second law

force= 50 N, acceleration equal 2 m/s^2

we want the mass

on a side note N(newton and its units are kg m/s^2, im giving oyu this so you can see how the units will cancel out and give you only weight units for the mass so you know you did it correctly)

50N = mass times 2 m/s^2

divide by 2 m/s^2

50N/(2 m/s^2) = mass

the m/s^2 cancels out the m/s^2 on the 50N leaving you with 25kg which is you answer because kg is a unit of weight right?
