Homework Statement


During an autumn storm, a 0.012kg hail stone traveling at 20.0m/s made a 0.20cm deep dent in the hood of Darnell's new car. What average force did the car exert to stop the damaging hail stone?
m= 0.012kg
v= 20m/s
d= .002m


Homework Equations


p=mv
j= f delta t


The Attempt at a Solution



I'm just confused :/
 
Physics news on Phys.org
Never mind, I was able to solve it. :D

.012kg * 1/2(20m/s)^2 / .002m = 1200 N

Too easy :)
 
Hello Marco! What is the relation between average force and change in momentum?
 
That's good!
