no help guys?
hey everyone,
im not here to just get answers because im lazy, im here because i got a 10 page notebook and ive done 90 pct of the questions and just a few is left. This question really confuses me, i just need help to solve it so i can be done
thnx if u help me(im new here)
A student designs a special container as a part of an egg drop experiment. she believes the container can withstand a fall as long as the speed of the container does not exceed 80 ft/s. shes uses this equation
v=sqrt(v_{0})^{2}+2ad (the whole thing is square root)
to model the velocity v, in feet per second, as a function of constant acceleration, a, in feet per second squared and the drop distance d in feet. the acceleration due to gravity is 32ft/s^{2}
a) will the egg break if the student drops the egg from shoulder height(5 ft) off a building 80 ft high?
i did so far
v=sqrt(v_{0})^{2}+2(32)(85)
b) what is the maximum height the egg can be dropped from?
Hello, EASYPEAAZY!
A student designs a special container as a part of an egg-drop experiment.
She believes the container can withstand a fall as long as the speed of the container does not exceed 80 ft/s.
She uses this equation: to model the velocity in ft/sec,
as a function of constant acceleration, and the drop distance in feet.
a) Will the egg break if the student drops the egg from shoulder height (5 ft) off a building 80 ft high?
I did so far:
Note that the egg is dropped.
That is: .
b) What is the maximum height the egg can be dropped from?
We have: .
Square: n . . . . .
Therefore: . . . . . .
a) so i solved it and got v=sqrt(64)(85).....-> v=sqrt(5440)----->v=73.76 ft/s...so it will not break (thnx mark and soroban)
^ tell me if its right
b) i did 80=sqrt(0^2+64d)---> 80^2=sqrt(64d)^2--> 6400=64d--->d=100... 100 is the maximum height that it will not break(its a lil different than what you did soroban)
tell me if those are right please(thnx to the 2 posters above me for giving me help)
