An Item weighing 1.5 lbs traveling at 20 meters per second will strike with how many PSI?

I've tried using every unit converter on the net...and I can just not figure this problem out...This is not a school question...just curiosityAn Item weighing 1.5 lbs traveling at 20 meters per second will strike with how many PSI?
to determine pressure u need two quantities Force and Area

Area will ofcourse depend upon the object

the force however, will depend upon the impulse and that something which is very difficult to figure out...you will need to determine how long the object was in touch with the ground, this value is usually in a few hundreths of a second

face book
