Which one of the following correctly expresses the impulse delivered by a time-dependent force

F(t)

acting from

t=t_1

t=t_2

? (a)

F\!\left(\dfrac{t_1+t_2}{2}\right)(t_2-t_1)

(b) The area under the

F

–

t

curve between

t_1

and

t_2

(i.e.

\displaystyle \int_{t_1}^{t_2} F(t)\,dt

) (c)

m\,\dfrac{v_1+v_2}{2}

(d)

m v_2
