What is an object of mass 15kg moving with velocity 4m s?

Mass of the object m = 15 kg Velocity of the object v = 4 m/s Ek = 1/2mv2 = 1/2 × 15 kg × 4 ms-1 × 4 ms-1 = 120 J The kinetic energy of the object is 120 J.

What is the kinetic energy of a 150kg object that is moving with a speed of 15 m sec?

Kg m^2 s^-2 = Joule ,so The kinetic energy of a body of mass 150 Kg moving at 15m/s is 16875 Joules.

How fast is the object moving if the object has a kinetic energy of 14 j and a mass of 17 kg?

v = 1.28 m/s.

What is the kinetic energy of a 45 kg object moving at 13?

What is the kinetic energy of a 45 kg object moving at 13 m/sec? 3. Solving the equation gives a kinetic energy value of 3802.5 J. Note: The unit for energy is the same as for work: the Joule (J).

What is the kinetic energy of a 10 kg object moving at 5 ms?

The kinetic energy of the object is 125 J.

What’s the formula for kinetic energy?

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

What is a mass of 10 kg moves with velocity of 4m s?

Answer and Explanation: K = 1 2 m v 2 = 1 2 ( 10 kg ) ( 4 m/s ) 2 = 80 J .

What is the kinetic energy of an object of mass 12kg is moving at a valiantly of 5mls?

K i n e t i c E n e r g y ( K E ) = 1 2 ∗ 12 ∗ ( 5 ) 2. KE = 150 J.

What is the speed of an object of 1 kg mass with a kinetic energy of 50 J?

Mass (m)= 1 kg. Velocity (v)= 10 m/s. ∴The Kinetic Energy of the object is 50 J. ∴ The correct option is the 4th.

How do you find the speed of an object with kinetic energy?

What is the kinetic energy of a car of mass 500kg moving with a velocity of 36km h?

Velocity of car, v = 36 km/hr = 36 × (5/18) = 10 m/s. Mass of car , m = 500 kg. Kinetic energy = (1/2) m v2 = (1/2) × 500 × 10 × 10 = 25000 J = 25 kJ. KInetic energy is proportional to square of velocity .

How fast is an object with a kinetic energy of 25 j and a mass of 34 kg?

∴ The velocity of the object is 1.21 m/sec.

What is the formula for the kinetic energy of the fastest electron?

The maximum kinetic energy of a photoelectron is given by 𝐸 = ℎ 𝑐 𝜆 − 𝑊 , m a x where ℎ is the Planck constant, 𝑐 is the speed of light, 𝜆 is the wavelength of the incident photon, and 𝑊 is the work function of the metal surface.

Does kinetic energy go faster?

The following equation is used to represent the kinetic energy (KE) of an object. This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four.

What is the kinetic energy of a body of mass 15 kg?

The kinetic energy of a body of mass 15 kg is 30j.

What would be the kinetic energy of an object of mass 20 kg is moving with uniform velocity 5 ms1?
