Vanessa pushes a box with 50 N of force. The box accelerates 2 m/s2 for 10 seconds. What is the mass of the box?
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?
