I am trying to work through this problem to no avail. Homework Statement A water-skier is moving at a speed of 12.5 m/s. When she skis in the same direction as a traveling wave, she springs upward every 0.498 s because of the wave crests. When she skis in the direction opposite to that in...

Hi all, I am having difficulty with a question. I would like some guidance. QUESTION: A block rests on a frictionless horizontal surface and is attached to a spring. When set into simple harmonic motion, the block oscillates back and forth with an angular frequency of 9.5 rad/s. The drawing...

Does anyone have any ideas for the 2nd and 3rd one? Thanks!

Do I use the same equation that I used in the beginning?

I am attempting 3 questions I have worked them out but to no avail. I wonder if I am on the right track: 1st Question: Starting from rest at the top, a child slides down the water slide at a swimming pool and enters the water at a final speed of 5.00 m/s. At what final speed would the...

Thanks for the response, I am thinking that I would use the Kinematics in one dimension type equation for this: V^2 = Vo^2 + 2ax Which would lead me to believe that the initial velocity should be the square of the original initial velocity that only made it half way. -Matt

Here is a problem I am having difficulty with: In attempting to pass the puck to a teammate, a hockey player gives it an initial speed of 2.89 m/s. However, this speed is inadequate to compensate for the kinetic friction between the puck and the ice. As a result, the puck travels only...

thanks, this was extremely helpful. But I am still confused as to where to start. with my given information: m = 364 kg r = 172 m v = 23.1 m/s So in using this information, I found the Centripetal force using: Fc = mv^2/r = Fc = 364(23.1^2)/172 = 1129.26 <----- this is correct. I was...

For the Doc...JK...some more questions using Centripetal Force A motorcycle has a constant speed of 23.1 m/s as it passes over the top of a hill whose radius of curvature is 172 m. The mass of the motorcycle and driver is 364 kg. Find the magnitude of (a) the centripetal force and (b) the...

I guess that's why they call you the Doc! Thanks so much, crystal clear explanation, I got the correct answer! :smile:

Thanks guys, but at this point we have not covered angular velocity in terms of centripetal acceleration, the problem should be able to be solved using these simple terms. Is there anything that I have done wrong? Based on my reasoning, the CD is rotating at a constant velocity, so finding...

Simple Question, Where am I going wrong!? The Question: A computer is reading data from a rotating CD-ROM. At a point that is 0.0251 m from the center of the disk, the centripetal acceleration is 250 m/s2. What is the centripetal acceleration at a point that is 0.0856 m from the center of...

Thank you very much, I have not taken energy yet so I don't know how to do it that way, plus your explanation still confused me :biggrin: but nonetheless, thanks so much for the time, I am going to try the second question now.

I have 2 questions that I am approaching, one seems very simple but I am still at a loss. The other I have attempted multiple times to no avail. Here they are: 1. An arrow, starting from rest, leaves the bow with a speed of 28.9 m/s. If the average force exerted on the arrow by the bow was...

thanks for all the help Andrew, I wasn't able to get it. the correct answer was 1.30. Thanks again though.
