Homework Statement A lead weight with a volume of 0.69x10^-5 m^3 is lowered on a fishing line into a lake to a depth of 1.0m. What tension is required in the fishing line to give the weight an upward acceleration of 1.8m/s^2? Homework Equations T=F-mg F=ma D=mv D of lead= 11.34gcm^3...

so i rechecked my calculations and still get the moment of inertia. how do i go from there though to solve for the number of rotations in the fall?

w=18.08314 and I=0.03888 and v=2.1699768. i keep getting that the rotational kinetic energy is ~4.23, but it keeps coming up as incorrect. are any of my preliminary calculations incorrect? but i'd have know correctly, w, v, and I to solve for the distance (which i know is correct). so I'm...

ohhh ok thanks! i'll see if that works. THANKS!

Ohhh really? I was looking online for that and haven't had any luck so far. I'll continue to look! Thanks!

to my knowledge no. cylinder: m= 1.8kg r= 0.12m l= 0.50m ramp: h= 0.6m l= 5.0m "A cylinder is released from rest at the top of a ramp and allowed to roll without slipping. What is the rotational kinetic energy?" I already correctly solved that the total kinetic energy at...

yes i would assume so. v=vo + at to w=wo + alphaT

My textbook is not helping me on this, so I'd love some help. A cylinder is rolling down a ramp, without slipping. I have the total kinetic energy, but now need to know the rotational kinetic energy and transitional kinetic energy at the bottom of the ramp. I have the mass, radius...

If I have a ball/sphere is released from rest, rolls (without slipping) down a ramp, then drops from the table the ramp is on, how many revolutions does the ball make during the fall? The diameter of the ball, height of the ramp, and height of the table are known. And I calculated the...
