A crate is pushed with 50 Newtons of force with an acceleration of 2 m/s^2. What is the mass of the crate?
25 kg. According to Newton's Second Law, the acceleration of an object depends on the net force acting on the object and the mass of the object. Put in mathematical terms, F=ma. 50N=(25kg)(2m/s^2)
