Find Momentum & Force of Pellet Penetrating Clay | Physics

[Procrastinate]

An air rifle pellet of mass one gram and velocity 100 metres per second penetrates five centimetres into a lump of clay and comes to rest in one millisecond. Assume that the force acting on the pellet when in clay is constant.

Find the magnitude of the change in momentum and the magnitude of the force acting on the pellet.

My answers were 1 x 10^-1kgms^-1 and 1 x 10²N but there aren't any solutions on the page, so I was wondering if I was right?

Looks like I got it right.I get the same answers as you.
