What is a 10.0 G bullet moving at 300m s is fired into?

What is a 10.0 G bullet moving at 300m s is fired into?

In a police ballistics test, a 10.0-g bullet moving at 300 m/s is fired into a 1.00-kg block at rest. The bullet goes through the block almost instantaneously and emerges with 50.0% of its original speed.

What is the average force of a 10 gram bullet moving at 200 meters per second stops after penetrating 5 cm of wooden

Average force F=mass×acceleration=. 001×400000=4000N Option C is correct.

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?

Can a bullet moving with a speed of 100 ms can just penetrate?

A bullet moving with a velocity of 100 m/s can just penetrate two planks of equal thickness.

What is a bullet of 10 grams moving with a velocity of 400 meters per second?

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 speed of a fired bullet?

A bullet is fired at a typical muzzle velocity of around 2,700 ft. per second, or around 3,000 kilometres per hour. Once the gases stop pushing it, it begins to slow down due to two forces – the resistance of the air that it’s pushing through, and the downward suck of gravity.

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 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 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 the velocity of a bullet of mass 20 g is fired from a rifle?

A bullet of mass 20 g is fired from a riffle with a velocity of 800 ms−1 . After passing through a mud wall 100 cm thick, velocity drops to 100 ms−1 .

What is the momentum of a bullet of mass 20 gram?

The momentum of a bullet of mass 20 g fired from a gun is 10 kg m/s.

Can a bullet lose velocity?

A bullet will accelerate until it leaves the barrel, typically around Mach 3. It will then immediately start decelerating at slightly more than 10 metres per second per second – gravity and air resistance will slow it down. At some point high in the air (work it out yourself) the bullet will stop and begin falling.

What speed is faster than a bullet?

Speed of light—faster than a speeding bullet.

Can a bullet travel faster than light?

However, compared to the speed of light, bullets are effectively standing still – light travels at about one million times faster than a 9-millimeter handgun round.

What is the speed of recoil of a 10g bullet shot from a 5kg gun with a velocity of 400m s?

By using this, 10grams or 0.01kg of bullet with speed 400 m/sec and 5kg gun recoil with speed suppose ‘v’. v=0.8m/sec ANSWER.

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 a bullet with a mass MB 12.3 G is fired into a block of wood at velocity?

A bullet with a mass 𝑚b=12.3 g is fired into a block of wood at velocity 𝑣b=249 m/s. The block is attached to a spring that has a spring constant 𝑘 of 205 N/m. The block and bullet continue to move, compressing the spring by 35.0 cm before the whole system momentarily comes to a stop.

What happens when a bullet of mass 10g is fired horizontally with a velocity of 400m s?

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.
