What is the kinetic energy of a 200kg boulder when it is 1000m above the ground?

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

What is the kinetic energy of a small 20 kilogram canoe is floating downriver at a speed of 2 meters per second?

What units are kinetic energy measured in?

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

What is the kinetic energy of an object that has a mass of 20 kg and a speed of 2.8m per second?

The object's kinetic energy is 78.4 joules.

How do you compare kinetic energies on things that move?

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.

Start with 20 joules if speed is doubled what is new kinetic energy?

80 (20 x 22).

What is a kinetic energy of an object that has mass of 20 kilograms and speed of 2.8ms?

78.4 joules at 2.8m/s

Why does kinetic energy depend on mass and speed?

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.

Is kinetic energy measured in mass?

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.

What is the similarities between kinetic energy and potential energy?

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

What is the kinetic energy of a 1 kg mass that is moving with a speed of 20 ms?

200 joules at 20m/s

What is an object's kinetic energy if air resistance is not a factor and weighs 0.6 kg and its potential energy is 27 joules?

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.
