What is the kinetic energy of a bullet of mass?

Kinetic energy m is the mass of the bullet. Although both mass and velocity contribute to the muzzle energy, the muzzle energy is proportional to the mass while proportional to the square of the velocity. The velocity of the bullet is a more important determinant of muzzle energy.

What is the equation for the kinetic energy of a mass m moving at a speed V?

The translational kinetic energy of an object of mass m moving at speed v is KE=12mv2 KE = 1 2 m v 2 .

What is the potential energy in a body of mass 10 kg kept on the top of a pole 20 meter height?

Answer: Masss= m = 2 kg; height = h= 20 m; g= 10 m/s2 (assumption, acceleration due to gravity); Potential Energy = mgh = 12*20*10 = 2400 Joules.

What is the capacity of a body to do work is called?

The energy of a body is its capacity to do work. Anything which is able to do work is said to possess energy. Energy is measured in the same unit as that of work, namely, Joule. Mechanical energy is of two types: Kinetic energy and Potential energy.

How do you calculate kinetic energy from mass and velocity?

Kinetic Energy. In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s 2.

What is the average resistance force of a 40G bullet?

A bullet of mass 40 g moving with a speed of 90 ms^-1 enters a heavy wooden block and is stopped after a distance of 60 cm. The average resistance force exerted by the block on the bullet is A bullet of mass 40 g moving with a speed of 90ms −1 enters a heavy wooden block and is stopped after a distance of 60 cm.

What is the kinetic energy of 10 kg?

For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s 2.

What is the average resistance force exerted by the block?

The average resistance force exerted by the block on the bullet is A bullet of mass 40 g moving with a speed of 90ms −1 enters a heavy wooden block and is stopped after a distance of 60 cm. The average resistance force exerted by the block on the bullet is
