# What is a bullet of mass 10g moving with a horizontal velocity of 400m s?

## What is a bullet of mass 10g moving with a horizontal velocity of 400m s?

A bullet of mass 10 g moving horizontally with a velocity of 400 m/s strikes a wooden block of mass 2 kg which is suspended by a 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 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.

## What is the magnitude of the force exerted by the wooden block on the bullet?

According to the third equation of motion: Hence, the distance of penetration of the bullet into the block is 2.25 m. Hence, the magnitude of force exerted by the wooden block on the bullet is 50 N.

## Which is having higher value of momentum a bullet of mass?

Answer: which is having a higher value of momentum A bullet of mass 10 g moving with a velocity of 400m/s or a cricket ball of mass 400g thrown with the speed of 90km/h? Therefore the cricket ball having the mass of 400 g and the speed of 90km/hr is having the higher value of momentum.

## 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.

## 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.

## How is the velocity of a bullet calculated?

Alternatively you could get a rough estimate of the bullet’s velocity by measuring the distance from the muzzle to a target and dividing this by the time it takes the bullet to reach the target, though there will be some loss due to air resistance. The best way to determine muzzle velocity is by using a chronograph.

## When a bullet of mass 10g is fired from a rifle the bullet takes?

Physics A bullet of mass 10 g is fired with a rifle. The bullet takes 0.003 s to move through its barrel and leaves it with a velocity of 300 m/s.

## What is the formula for the force of a bullet?

And then to get the Force of the bullet: F = m*a. F = 0.004 * 671232.87. F = 2684N.

## What is the formula for the friction force on a block?

As P is continually increased, the block will now slip, with the friction force acting on the block being: f = muK*N, where muK is the coefficient of kinetic friction, with f remaining constant thereafter as P is increased.

## What force is exerted on the bullet by the rifle?

Force exerted on the bullet by the rifle will be, F = m a = 10 – 2 × 10 5 = 10 3 N . Q. A bullet of mass 10 g is fired from a rifle.

## What is the SI unit of momentum?

Momentum
SI unit kilogram meter per second (kg⋅m/s)
Common symbols p, p
Other units slug⋅ft/s
Dimension MLT1

## Which is having higher momentum a bullet of mass 10g?

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.

## Does momentum increase mass?

Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.

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

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

## 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.

## 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.
