A 0.25 kg baseball is in contact with a bat for 0.0075 s and exerts a force of 18,500 N. What impulse is delivered to the ball?

The other answer is correct, but when on the site is asks for that answer rounded so it would be 140.

The answer is 138.75 kgm/s

Impulse (I) is the multiplication of force (F) and time interval (Δt) : I = F · Δt

It is given:

m = 0.25

F = 18,500 N = 18,500 kgm/s²

Δt = 0.0075 s

I = ?

I = F · Δt = 18,500 5kgm/s² * 0.0075 s = 18,500 * 0.0075 kgm/s² * s = 138.75 kgm/s
