Question

by what factor does thd kinetic factor of a moving body change,when its speed is reduced to one third of the initial velocity?plz answer fast

Answer 1

The factor by which the kinetic energy of a moving body changes when its speed is reduced to half. 0. Physics. Related Questions: A particle starts S.H.M. from the .

Answer 2

as kineticenergy KE is directly proportional to velocity square
change in KE=0.5(mv²)
=0.5(9mu²)
v=3u
initial KE =0.5(mu²)
so change is
1/9
