Egg drop project
Calculate (metric): Velocity, Time, Mass, Height Acceleration, Impact force
height of tower: 80 ft
weight of egg: 25 oz
A little unclear....do you need to convert everything into metric? Or leave it in SAE?
First of all your parameters are NOT metric, so I will proceed with SAE
Acouple of equations that you should know and will need:
pf = po + vt + 1/2 a t^2
" Position(final) equals ORIGINAL position plus velocity times time plus 1/2 acceleration times time squared."
vf = vo + at Velocity(final) equals original velocity plus acceleation times time
po = 80 ft pf=0 vo=0 a = -32 ft/sec^2
pf= po + vt + 1/2 at^2 Substituting:
0 = 80 + (o)t + 1/2 (-32) t^2 Solving for t results in t=2.236 seconds for the egg to go 'splat'
Substitute THIS value of 't' into the second equation to see how fast it is going at impact:
vf= 0 + at = - 32(2.236) = 71.554 ft/sec DOWNWARD.
