What of the following objects are moving at the same speed. which one has greatest kinetic energy. a.) a semi tractor-trailer truck b.) a car c.) a motorcycle d.) a bicycle

Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?
