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’s the total change in momentum of the object from time t = 5 until t = 7 seconds?

A) 0.402 newton•sec
B) 0.708 newton•sec <----
C) 0.909 newton•sec
D) 1.416 newton•sec
E) 1.616 newton•sec

• Calculus -

integral f(t) dt from 5 to 7

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.
