ii) Apply conservation of energy, making sure you count both translational and rotational KE now with this part Im not sure what you mean? i understand the conservation of energy but that wont give me the speed of the wheel
Physics
(b) Given that Icm = ½MR2 for a uniform solid wheel, (i) show that the rotational kinetic energy is half the translational kinetic energy for such a wheel. (ii) For the wheel of diameter 10 cm, find its final speed after traversing a distance of 10 m down an incline of...

how did u find the angular velocity? im tryin to use v = wr but i dont know where to find the normal velocity of the rim
physics
no i mean to convert 45degrees into rads you multiply by 2pi thanks for your help
physics
so for the first part 20N * 0.2m * 2pi is that correct? also how did you get your torque? (iii) What is the angular momentum of the wheel after this time?
physics
A constant force of 20N is applied tangentially to a string wound on the rim of a 40 cm diameter wheel, initially at rest. (i) How much work does this force do as it turns the wheel through 45„a? (3 %) (ii) If the wheel has mass 8.0 kg and radius of gyration 15 cm, how lo...
