I tried using 0 as well, but that answer isn't right either. I know the final answer is -.335 m/s...

Homework Statement A 450 g object oscillates from a vertically hanging light spring once every .55 s. The object is released with the spring compressed by 10 cm from the equilibrium position. What is the velocity of the object 3.00 s after it is released? Homework Equations...

So was I right to put the amplitude in for xo and then for \omega what would I use to plug in for that, is it 2pi/T?

Homework Statement I have been stuck on this question for quite some time. I'm trying to study for the test and actually have the answer, but I can't figure it out. The answer is 1.3X10-6cm/s2 The following graph represents an object oscillating in simple harmonic motion. What is the...

So obviously there is another equation that I need to use obviously...any nudge on what the equation I would use? Will I be using a type of Trig equation? You said that I would need to factor in sin(theta) but I still need the height. So I won't replace the height with sin(theta), but will still...

Homework Statement An all-terrain vehicle with a 2,000 kg mass moves up a 15o slope at a constant velocity of 6 m/s. What is the rate of change of gravitational potential energy with time? Homework Equations W=\DeltaE/\Deltat W=FXd Ki+Ui=Ki+Ui (I think that's what it is) Pe=mgh...

The book was doing the same type of problem, but with the sun instead of the moon and it said the R in 1/R was the radius of the sun+the radius of the Earth and then you subtracted 1/r (from 1/R) and r being the distance between the sun and the earth. Then you multiplied that answer by 2GM and...

Apparently not...the book was showing the R was the radius and r was the distance between the moon and the earth

So for the second part would I do the same equation, but instead of having (1/Rmoon+Rearth)-1/r(distance between moon&earth), would I change the Rmoon+Rearth to the initial position t+final position and then subtract from the center of the earth?

the Rmoon is the radius of the moon...I didn't really know how to do the first part of the problem, but I looked through the book and followed a problem that was similar to the first part and got the right answer and understand the first part now, but there was nothing really how to do the...

Homework Statement Two meteoroids are heading for earth. Their speeds as they cross the moon's orbit are 2.0 km/s. The first meteoroid is heading straight for earth. What is its speed of impact? The second misses the Earth by 5000 km. What is its speed at its closest point? Homework...
