# What is a bullet of mass 10g moving horizontally with a velocity of 400?

## What is a bullet of mass 10g moving horizontally with a velocity of 400?

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.

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

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

## 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.

## 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 kinetic energy of a 0.02 kg bullet?

E = 1 2 . ( 0.02 ) ( 300 ) 2 = 900 J.

## What is the rate of bullets of mass 0.03 kg is hit a plate at?

Bullets of 0.03 kg mass each hit a plate at the rate of 200 bullets per second, with a velocity of 50 m/s and reflect back with a velocity of 30 m/s. The average force acting on the plate is. Was this answer helpful? A bullet of mass 0.03 kg and moving with velocity ‘x’ hits a target with a force of 187.5 N.

## 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 average force is necessary to stop a bullet with a mass of 0.02 kg?

It has to be converted into the SI unit. So the mass becomes . 02 kg. So \[5.2kN\] force required to stop the bullet.

## 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 22 projectile speed?

The velocity of standard-velocity . 22 LR rounds varies between manufacturers. Some standard velocity ammo may be slightly supersonic-around 1,125 ft/s (343 m/s), other ammo such as CCI Standard Velocity . 22 LR ammunition is rated at 1,070 ft/s (330 m/s).

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

∴ Kinetic energy = 80 J and momentum = 40 kgms−1. Q. A body of mass 10 kg is moving with velocity 4 m/s. If P is the momentum associated with the body and K.E. is the kinetic energy.

## 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.
