So, here is the problem:
I have a .535kg ball that I drop from an unkown height, to create an impact with a force of 6.8 Joules.
I need to figure out what height to drop the ball from.
I figure it has something to do with accleration due to gravity and Netwons law F=mA or possibly a...
Still unclear...
So if the Mass of the sphere (M) = 1.18 lbs = .535kg & the impact force = 5 ft. lbs. = 6.8 Joules, then is the velocity = to acceleration by gravity ~ 9.8m/s^2?
So it's .5(.535kg * (9.8 m/s^2)) = 6.8 Joules ??
Hello,
I am probably going to suffer some embarassment, once I see the answer to my question. Anwyay, I need to calculate the distance needed to create a 5ft-lbs. impact with a 1.18lb. sphere being dropped vertically onto a surface.
How would I go about calucating the vertical distance...
