Kinetic energy = 1/2 (mass) (speed)2 = 1/2 (0.2) (200)2 = 4,000 joules

To measure kinetic energy:Let us suppose an object of mass m moving wtih velocity vKinetic Energy of that object= mv2/2

200 joules at 20m/s

I think the quantities involved are Mass Speed and Kinetic energy transfered but I'm not sure

That's called kinetic energy. The formula is: Kinetic energy = (1/2) x mass x velocity2. If mass is in kilograms, and velocity (or speed, really) in meters per second, the energy will be in Joules.

The object's kinetic energy is 78.4 joules.

Kinetic energy = (1/2)*mass*(speed)^2 where, in metric units, mass is in kilograms, speed is in meters/second, and kinetic energy is in Joules. So, you need to know the mass and the speed of the things.

Since kintetic energy is the energy of motion it depends on the two. mass affects inertia and inertia applies to kinetic energy. and speed is applied because the faster it going the more kinetic energy the object has.

The kinetic energy of any moving object is 1/2 of (its mass) x (the square of its speed). The SI unit of any kind of energy is Joules.

kinetic energy depends on speed an potential energy depends on height and mass

The object's kinetic energy can't be determined from the given information. Kinetic energy = (1/2) (mass) (speed)2 The question gives the object's mass, but we need its speed too.
