What is the kinetic energy of mass of 30 kilograms that moves with a velocity of 15ms?
Potential Energy equals One Half Mass times Velocity squared. 30kg X 15m/sec X15m/sec =6750 Joules
What is the Kinetic Energy of an object with a mass of 175 Kilograms and a velocity of 3 meters per second?
Kinetic energy = 1/2(mass in kg)(meters per second squared ) KE = 1/2(175 kilograms)(3 m/s)^2 = 787.5 Joules
The amount of energy an object contains and how fast the particles of matter move is?
Kinetic energy = 1/2mv2, where kinetic energy is measured in Joules, mass in grams, and velocity in m/s.
How will the momentum of a body changes if its Kinetic energy is doubled?
Let's see. Mass constant. 625000 Joules = 1/2(500 kg)V2 1250000 Joules = 500V2 2500 = V2 50 meters/second = velocity ==================================== The velocity doubles if KE doubles.
What is the kinetic energy of an 8kg mass traveling at 5 meters per second?
Velocity of 4 meters per second??? I will assume so. ( need kilograms, so... 5 grams = 0.005 kilograms ) KE = 1/2mV2 KE = 1/2(0.005 kg)(4 m/s)2 = 0.04 Joules =============
How fast will an object be moving if its kinetic energy is 300 joules and has a mass of 0.05 kilograms?
The object's velocity will be 109.54 meters per second.
The kinetic energy of the object moving with a velocity of 5 meter per second is 25 joules. What will be the kinetic energy when the velocity is tripled?
The object has a mass of 2kg. When velocity is tripled the kinetic energy becomes 225 joules.
Calculate the kinetic energy in joules of an automobile weighing 2135 lb and traveling at 55 mph?
The kinetic energy in joules of an automobile weighing 2135 lb and traveling at 55 mph is 2.9 x 105.
What will be the kinetic energy and velocity of object of mass 62kg?
Its kinetic energy (in joules) will be (31) times (its velocity in meters per second)2 .
What is the energy of a system by virtue of its motion?
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.
What is the kinetic energy of mass of 30 kilograms that moves with a velocity of 15ms?
Potential Energy equals One Half Mass times Velocity squared. 30kg X 15m/sec X15m/sec =6750 Joules
What is the Kinetic Energy of an object with a mass of 175 Kilograms and a velocity of 3 meters per second?
Kinetic energy = 1/2(mass in kg)(meters per second squared ) KE = 1/2(175 kilograms)(3 m/s)^2 = 787.5 Joules
What is the kinetic energy of an object with an mass of 5 grams and a velocity of 1000ms?
The object's kinetic energy is 2,500 joules.
What is the kinetic energy of a bicyclewith mass 10 kg traveling at a velocity of 3ms?
The bike's kinetic energy is 45 joules.
How factors are used to calculate the kinetic energy of an object?
KE = (1/2)mv2 where m = mass (in kilograms), and v = velocity (in meters/second) this gives you the kinetic energy in units of Joules
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
How do you calculate mass when given joules and velocity?
Kinetic energy = (1/2) (mass) (velocity squared)Divide each sideby (velocity squared/2): Mass in kg = ( 2 x energy in joules) / (velocity in m/s) squared
