When you double the velocity, you the kinetic energy.
a. quadruple
b. double
c. halve
d. multiply

Quadruple

Explanation:

Kinetic energy is the energy possessed by a body by virtue of its motion. It is represented mathematically as 1/2MV². If

(KE)1 = 1/2MV1²...(1) where;

M is the mass of the body

V is the velocity of the body

If the velocity is now doubled i.e V2 = 2V1 the Kinetic energy becomes

(KE)2 = 1/2M(2V1)²...(2)

Note that the mass doesn't change

Dividing equation 2 by 1, we have;

Ke2/Ke1 = 1/2×4MV1²÷ 1/2MV1²

Ke2/Ke1 = 2MV1×2/MV1

Ke2/Ke1 = 4

Ke2 = 4Ke1

This shows that when you double the velocity of an object, you quadruple its kinetic energy.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
