What is a bullet of mass 10 gram moving horizontally with velocity of 400 m per second strikes a wood block of

A bullet of mass 10 g moving horizontally with a velocity of 400 ms−1 strikes a wooden block of mass 2 kg which is suspended by light inextensible string of length 5 m. As a result, the centre of gravity of the block is found to rise a vertical distance of 10 cm.

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 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 bullet of mass 10g moving with a velocity of 400m s or a cricket ball?

Solution: A bullet of mass 10 g moving with the velocity of 400 m/s and a cricket ball of mass 400 g thrown with the speed of 90 km/h . Then the cricket ball has higher momentum. =10 kg ms-1 Thus, the cricket ball has higher momentum.

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).

What is the SI unit of the Boltzmann constant?

The Boltzmann constant relates an object’s energy to its temperature. In the revised SI, the Boltzmann constant k equals 1.380649 × 10-23 joules/kelvin. k will help to define the kelvin.

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

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

What is the momentum of bullet of mass 0.02 kg?

(b) a bullet of mass 0.02 kg moving at 400 m/s. Therefore, the momentum of the elephant is 10000 kg−m/s 10000 k g − m / s . Therefore, the momentum of the bullet is 8 kg−m/s 8 k g − m / s .

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 50 grams moving with a speed of?

Hence there is an average retarding force of 62500N. Was this answer helpful? A bullet of mass 50 g is moving with a velocity of 500 m/s. If it penetrates into a 10 cm still target and comes to rest.

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 speed of a bullet of mass 40 g with kinetic energy equal to 200 J ___ MS − 1?

Speed v=√2×K. Em = √2×2000.04 = 100 ms−1.

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.
