The kinetic energy, k, of an object with mass m moving with velocity v can be found using the formula - e_{\text{k}}={\tfrac {1}{2}}mv^{2} . a scientist measured the velocity of a 5-kilogram object and a 20-kilogram object in an experiment. if the velocity of the 5-kilogram object was twice the velocity of the 20-kilogram object, what was the ratio of the kinetic energy of the 5 kilogram object to the kinetic energy of the 20-kilogram object?

In physics, the kinetic energy of a moving object is given by the formula k=1/2mv^2 where m is the mass of the object and v is the object's velocity. suppose a rocket is increasing in velocity at 10m/sec^2, and is decreasing in mass at 15kg/sec because it is using up fuel. how fast is it's total kinetic energy changing when the velocity is 30m/sec and the mass is 1000kg? round to the nearest tenth.

)in physics, an object that is in motion is said to have kinetic energy. the following formula can be used to determine a moving object’s kinetic energy: ke = ½ mv2 the variables in the formula are as follows: ke is the kinetic energy, m is the object’s mass in kilograms, and v is the object’s velocity, in meters per second. write a method named kineticenergy that accepts an object’s mass (in kilograms) and velocity (in meters per second) as arguments. the method should return the amount of kinetic energy that the object has. demonstrate the method by calling it in a program that asks the user to enter values for mass and velocity.
