Can someone check my answer?

The change in the momentum of an object (Δ p) is given by the force, F, acting on the object multiplied by the time interval that the force was acting: Δ p = F Δt .

If the force (in newtons) acting on a particular object is given by F(t)=cost , what痴 the total change in momentum of the object from time t = 5 until t = 7 seconds?

A) 0.402 newton不ec

B) 0.708 newton不ec <----

C) 0.909 newton不ec

D) 1.416 newton不ec

E) 1.616 newton不ec
