Since the hoop is rolling on the floor so its total kinetic energy is given as
now for pure rolling condition we will have
also we have
now we will have
now by work energy theorem we can say
now solve for final speed
Answer:
60,000m
Explanation:
Convert km/h to m/s by multiplying with 1000/3600.
Convert hours to seconds by multiplying with 3600.
