On object has 25 Joules of Kinetic Energy. If the velocity of the object is doubled, what would be the result of the Kinetic Energy?

The kinetic energy would quadruple. See the explanation below, please.

Explanation:

We use the formula of kinetic energy formula is:

Ec = 1/2 m x v ^ 2. . Take as an example a speed of 1m / s, and calculate the body mass:

25 J = 1/2 m x (1m / s) ^ 2 -> m = 25kgxm2 / s2x2 / 1 m2 / s2 = 50 kg

1J = 1 kgxm2 / s2

For a doubled speed: 2m / 2

Ec = 1/2 x 50kg x (2 m / s) 2 = 100J

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
