Question

an object has a mass of 12kg and its traveling at 5m/s. what happens to its kinetic energy if the speed is increased to 15 m/s?

Answer 1

\[KE=1\div2\left( m \right)\]
then put V=5 m/sec and V=15m/sec and compare both result and get your answer..

Answer 2

\[KE=(1\div2)MV ^{2}\]

Answer 3

where did u get the 2 from

Answer 4

this is formula...

Answer 5

put and find kinetic energy...
