Question

A mass attached to a spring vibrates 15 times in 22.23 seconds. What is the linear frequency (in Hertz) of the mass?

Answer 1

Frequency is times/second, so 15/22.23 I think

Answer 2

thank you!

Answer 3

also! I have a quick question!

Answer 4

when looking at a simple harmonics graph, how would you calculate the maximum velocity?

Answer 5

anyone?

Answer 6

pretty please.

Answer 7

Vmax is the slope of the graph of position vs time as it crosses the equilibrium position

Answer 8

so for this graph https://elearning2.courses.ufl.edu/samigo-app/servlet/ShowAttachmentMedia?actionMode=preview&resourceId=%2Fattachment%2F75cef42f-fb2b-4a50-b307-64b46082b892%2FTests+_+Quizzes%2Fa173b7ec-157b-462a-9aa0-2d351991052f%2FFA+Prelab.jpg&mimeType=image/jpeg&filename=FA%20Prelab.jpg it would be 10?

Answer 9

find potential energy at a point where the object changes direction. At the point where vel. is max, all of this energy will be kinetic. Use kinetic formula to solve for max. vel.

Answer 10

oh eek.

Answer 11

I can't see the image.

Answer 12

:( oh well

Answer 14

how about there?

Answer 15

another error, sorry

Answer 16

oh ok. that's alright. so I wouldn't be able to do it with just the slope?

Answer 17

from a max peak to a min peak?

Answer 18

you could do it like stan said also

Answer 19

oh ok, wonderful thank you so much!
