Kinetic energy E = 1/2 m v2
So v = ./(2 E / m)
E = 7.5 J and m = 0.082 kg.
Plugging and simplifying, we get
v = 13.525 m/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.
What is the speed of an object increases its kinetic energy .?
The kinetic energy depends on both mass and speed. If either mass or speed increase, the kinetic energy will increase as well.
What increases as the speed of an object increases?
the kinetic energy of the object
Which has more kinetic energy- A small object or a large object moving at the speed of 25 mph?
You don't say what speed the small object has. If both have the same speed then the heavier one will have more kinetic energy.
When kinetic energy increases what happens to the mass and velocity?
Kinetic energy of a mass is directly proportional to two variables: its mass and speed. Many mistake kinetic energy as being proportional to mass and velocity; it is, in fact, mass and speed. (With all technicalities aside, the speed is the factor that matters in computing kinetic energy of an object or a mass). Kinetic Energy = 0.5mv2 (m = mass and v = speed of the mass) Therefore, if the speed of the object increases, the kinetic energy increases. If the speed of the object decreases, the kinetic energy decreases. Similarly, if the mass of the object increases while traveling, its kinetic energy increases. If the mass of the object decreases, the kinetic energy decreases. All has to do with the directly proportional relationship between the two variables and the kinetic energy.
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.
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 a kinetic energy of an object that has mass of 20 kilograms and speed of 2.8ms?
78.4 joules at 2.8m/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.
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 2 factors does the kinetic energy depend on?
It depends on mass and velocity. ans : it depends on the mass & speed of the moving object. no, it depends on the work & energy.
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
If the speed of an object doubles the kinetic energy of the object?
At twice the speed, the kinetic energy will be four times greater.
How does kinetic energy affect speed?
The kinetic energy of an object is proportional to the square of its speed.
If speed is tripled then its kinetic energy of a mass is?
The formula for Kinetic Energy of an object is mv2/2 where m: mass of object and v:velocity of object Therefore when the speed of an object is tripled, then its kinetic energy becomes 9 times
What The build up of speed in a moving object?
Potential energy, which can be released as kinetic energy. Kinetic energy not the build up of speed in a moving object.
What is the speed of an object increases its kinetic energy .?
The kinetic energy depends on both mass and speed. If either mass or speed increase, the kinetic energy will increase as well.
