this question can be answered by combining the equations for impulse and work done.
1. The equation for impulse derives from Newton's second law of motion:
F
=
Δ
p
Δ
t
⇒
Δ
p
=
F
Δ
t
Δp is the change of momentum, which is referred to as "impulse".
2. The equation for work done is:
W
=
F
d
d is the distance moved in the direction of the force.
3. If we substitute for force, F, we can combine the equations:
Δ
p
=
F
Δ
t
=
W
Δ
t
d
