OK I get it. Thanks guys. I use the measurement of the x,y co-ordinates and then sin(inverse) to find angle. Then calculate difference in angle between the two spots per difference in time which would give me the angular velocity.
Homework Statement
Calculating solar of the sun through observing sunspots. We are given a series of photos of the sun over a period of time where we can see sun spots.
I am assuming the way to calculate would be to work out the longitudinal angles of the sun spots in the different photos and...
oh sorry, for B) I get v= √(v0^2)/2. start with .5 mv0^2= .5 2mv^2 (masses and halves cancel out).actually the formula of K isn't given. I am assuming "energy conservation" refers to Kinetic energy
Sorry didn't make myself clear. what I did was tried putting values on both sides, like this for p for instance.
mv0= 2mv (here m cancel out). so the value of v in conservation of momentum according to this would be v0/2, essentially half of v0, which seemed pretty intuitive to me, but I've...
Homework Statement
This is the question show that when one of the steel balls, suspended by strings next to
each other (as in a Newton's cradle), is pulled to the left and released, only a single ball recoils to
the right under ideal elastic-collision conditions. Assume that each ball has a...
Thanks jackarms & SammyS.I do know kinematics equations, for some reason it never occurred to me that since the force is the same in both so must be the acceleration
Homework Statement
A runner exerts a constant force to accelerate from rest to 2.0 m/s over a distance of 12 m.
Assuming the runner can keep up the same force, what total distance would be needed to ac-
celerate up from rest to 3.0 m/s?
Homework Equations
none given.
