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

sin 7 - sin 5 = .657 - .959 = -.30 if angle is in radians

or

.121 - .087 = .0347 if angle is in degrees

I suspect you left a pi out or something.
