The kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s is j.
(formula: ke = 1/2 mv2 )

25

Explanation:

ke=1/2mv^2

kE=1/2(0.5×(10)^)

=1/2(0.5×100)

=1/2(50)

=25

explanation:

the panel also concluded there's a better than 95 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in earth's temperatures over the past 50 years.
