G force; physics question - help
Folks, I need some help. Here's the question;
I have a 1600KG crate. The "shockwatch" indicator shows 5G. How many meters (or feet) would I have to drop those 1600KG in order to get 5G's worth of "shock". I know G is a measure of acceleration.
I've got as far as 5 x 1600 = 8000Nm Force or 1600x(5Gx9.81Nm)/s=49ms/s/s Acceleration
Time must be the missing link, but how the heck to get it?
(PS 20 years since my last physics lesson - was a miserable student).
Thanks in advance
