A constant resultant force F F\,F acts on an object of mass m m\,m for a time interval Δt\Delta tΔt. During this time, the velocity of the object changes from v1 v_1\,v1 to v2v_2v2.
Which of the following equations correctly relates these quantities?
FΔt=m(v1−v2)F \Delta t = m(v_1 - v_2)FΔt=m(v1−v2)
FΔt=m(v2−v1)F \Delta t = m(v_2 - v_1)FΔt=m(v2−v1)
Fm=Δt(v2−v1)F m = \Delta t(v_2 - v_1)Fm=Δt(v2−v1)
F=mΔt(v2−v1)F = m \Delta t (v_2 - v_1)F=mΔt(v2−v1)
