Question

Hiii can someone help me with this physics problem? I know its SUPER easy because the answer 24,000 J but anyone wanna explain how? (Physics isnt my strongest point :P) BTW I need help with numba 50!

Answer 1

Remember that in a system where there are no non-conservative forces (like friction), work is simply:
\[W=-\Delta U_g\]Where, U_g, remember, is:\[\Delta U_g = mgh\]

Answer 2

Or, alternatively:

Answer 3

I understand, thank you! :)

Answer 4

@natasha.aries I have been able to 24090 J or also 2.4 x 10 ^ 4 or 24000, depending on how you regard for decimal numbers

Answer 5

how did you get 24000?

Answer 6

24090 J = 2.4 x 10 ^4, right??? (You can get a little neglect number 9)

2.4 x 10^4 = 24000 J..,


differences in the results of this figure stems from how thorough you take the value of sin 35

which one you choose?
sin 35 = 0.5735764
sin 35 = 0.5736
sin 35 = 0.574
sin 35 = 0.57

???

which one you choose??

your choice determines the answer

Answer 7

Can someone help me with this problem as well? Im pretty sure its the last problem! The last part says... When released, the block leaves the spring and travels upward vertically. How high does the it rise above the point of release?

Answer 8

Thank you @gerryliyana and @Xishem !!!

Answer 9

ur welcome

@natasha.aries : show the next sheet of number 43

Answer 10

It says When released, the block leaves the spring and travels upward vertically. How high does the it rise above the point of release?
Would you still like me to show it?
