Can someone help me calculate this? your mass (kg) × acceleration of gravity (9.81m/s/s) = your weight (N) your weight (N) × height of board (m) = work done in stepping up onto board
Your mass (68) = your mass in lbs 150/2.2 ) Use a bathroom scale to get you mass in lbs.
Would it be (68) x (9.81,/s/s) = 150 (150) x (24) =_______ Did I arrange that correctly?
The height of the board is 24cm
24cm = 0.24m always use metres in calculations
Ooops, yeah. So I did, set it up right though?
Looks like it
68 times 9.8 is definitely not 150. You should be able to tell, by estimating, noticing that 68*10 = 680... 150 is not close
Nuu 150 is my weight, and 68 is my weight in kg
8.9 is the time it took me so replace that with 9.8.
(68) x (9.81,/s/s) =???
That's your weight in Newtons. Multiply it by the height
No, scroll back to my very first post
Wait, I don't see what I did wrong, I multiplied the height.
Again, see my first post...
(68) x (8.9,/s/s) = 667.08 (667.08) x (0.24) = 160.0992
Gravity is 9.8 not 8.9
Oh I thought it meant the acceleration of the speed. . .Between the reps I was doing. Eh, confused.
It looks correct, as long as you used 9.8 and not 8.9.
Okay, thank you.
(68) x (8.9,/s/s) = 666.4 (666.4) x (0.24) =159.936
You are still using 8.9 for some reason...
The time has to be different otherwise my trials will be the same.
Look what you originally posted: your mass (kg) × acceleration of gravity (9.81m/s/s) = your weight (N) your weight (N) × height of board (m) = work done in stepping up onto board
It's not time, it's gravity. You posted it right at the top.
I dun know it wouldn't make sense then, because I have two trials, if I used the same number it would give me the same result, can't be right. I'm thinking it means my time and speed.
Trial Height of board (m)24(M)>0.24 Weight (n)150(N) Work for 1 repetition (J)129.2(J) Time for 20 repetitions (S)8.9(s) Work for 20 repetitions (J)2584(J) Power for 20 repetitions (J/s)290.337(J/s)
