When a bullet of mass 10 gram moving with a velocity of 400 metre per second gets embedded?

When a bullet of mass 10 gram moving with a velocity of 400 metre per second gets embedded?

Thus, the velocity acquired by the wooden block (having the bullet embedded in it) is 4.4 metres per second.

How do you find kinetic energy from calories?

– Kinetic energy is given as, $K.E.=\dfrac{3}{2}nRT$ where n is the number of moles, T is the temperature and R is the universal gas constant which is $R=1.9872 cal{{K}^{-1}}mo{{l}^{-1}}$. – Therefore, kinetic energy for a mole of ideal gas in calories is approximately equal to three times its absolute temperature.

What is the velocity of a bullet of mass 20 g is horizontally fired?

∴recoil velocity = 1.5 m/s. A bullet of mass 20g is horizontally fired with a horizontal velocity 150m/s from a pistol of mass 2kg.

What is a bullet of mass 0.2 kg moving at 400m s?

answer is 80kgm/s. Explanation: momentum = mass *velocity.

Is there a formula for kinetic energy?

Kinetic energy is energy possessed by an object in motion. The earth revolving around the sun, you walking down the street, and molecules moving in space all have 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.

How do you find the kinetic energy of a bullet?

Based on the general equation for kinetic energy, Ek=½mv2, which directly uses mass (m) and velocity (v), the following formula is used to calculate the kinetic energy of a projectile (expressed in foot-pounds): E=(W*V2)/(14000*gc).

How do you calculate kinetic energy step by step?

Step 1: List the given mass and velocity of the object. Step 2: If necessary, convert the mass and velocity values so they have units of kilograms and meters per second, respectively. Step 3: Calculate the kinetic energy of the object using the equation K = 0.5 m v 2 .

What is a 20 g bullet moving at 1000 m s is fired through?

A 20g bullet moving at 1000 m/s is fired through a one kg block of wood emerging at a speed of 100m/s. What is the kinetic energy of the block that results from the collision if the block had not been moving prior to the collision and was free to move? Answer is . 16 kJ, how do you get it?

What is the formula for projectile motion thrown horizontally?

(b) The equation that describes the horizontal motion is x=x0+vxt. x = x 0 + v x t . With x0=0, x 0 = 0 , this equation becomes x=vxt.

What is the formula for velocity in horizontal projectile motion?

Formula: Equations of Motion We can analyze the horizontal and vertical components of the particle’s motion separately. A horizontally projected particle moving freely under gravity has no horizontal acceleration. Therefore, its horizontal velocity does not change, so in the horizontal direction, 𝑣 = 𝑢 and 𝑠 = 𝑢 𝑡 .

What is a bullet of mass 15 g has a speed of 400 ms?

Expert-Verified Answer. A bullet of mass 15 g has a speed of 400 m/s. What is its kinetic energy ? = 1200 J Ans.

What is a bullet of mass 0.03 kg moving with a velocity of 400?

A bullet of mass 0.03 kg moving with a speed of 400 m/s penetrates 12 cm into fixed block of wond Calculate the average force exerted by the wood on the bullet. [Ans. 2 x 104 N.

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

An object of mass 10 kg is moving with a uniform velocity of 4 ms-1. The kinetic energy possessed by the object is 80 J.

What is a bullet of mass 10g is fired from a gun of mass 1kg with velocity?

or v1=500m/s. Was this answer helpful?

What is the initial velocity of a bullet of mass 10g?

A bullet of 10 g mass comes out with an initial velocity of 1000 m/s and strikes the earth at a velocity of 500 m/s at the same level.
