A 5.0-kg body has three times the kinetic energy of an 8.0-kg body. Calculate the ratio of the speeds of these bodies.

the ratio of velocity is equal to 2.2

Explanation:

given,

mass of the body, m₁ = 5 Kg

mass of the another body, m₂ = 8 Kg

KE₁ = 3 KE₂

we know,

now,

For first body

For second body

ration of the speed

Hence, the ratio of velocity is equal to 2.2

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

this would be about 43%
