If the kinetic energy of a 10 kilogram object is 2000 Joules, its velocity is ?

10 m/s.


20 m/s.


100 m/s.


400 m/s.


If the kinetic energy of a 10 kilogram object is 2000 Joules, its velocity is ?
KE = 1/2 mv^2





2000 = 1/2 10kg v^2





20m/s = vIf the kinetic energy of a 10 kilogram object is 2000 Joules, its velocity is ?
2,000kJ / (0.5 x 10) = v虏


v = 鈭?00 = 20m/s
