Would you care to fire a gun that has a bullet 10 times as massive as the gun? No. The gun would recoil with a speed ten times the muzzle velocity. … The forces are equal and opposite, by Newton’s third law, and the times are the same, so the impulses are equal and opposite.
Would it be safe to fire a gun that has a bullet that is 10 times more massive than the gun itself discuss and defend your answer?
Would you be safe in firing a gun that has a bullet 10 times as massive as the gun? Explain. No. The gun would recoil with a speed ten times the muzzle velocity.
Which has a greater momentum after a gun is fired the gun or the bullet which has a greater speed which has a greater energy?
So, the total momentum of the system before the bullet is fired is zero. After Firing: After the gun is fired, the bullet gets a velocity to the right, as shown. This means that the bullet now has momentum, mv, to the right.
Why does a small bullet have a large momentum?
When the mass is greater (at the same speeds), the momentum is greater. A bullet is an example of an object with a very small mass that has a lot of momentum because it is moving very quickly.
When a supertanker is brought to a stop its engines are typically cut off about 25km from Port Why is it so difficult to stop or turn a supertanker?
To bring an oil-tanker to a stop, its engines are typically cut off about 25 km from port. Why is it so difficult to stop or turn a supertanker? A supertanker has a huge mass, and therefore its momentum is enormous.
Do guns protect you?
In short, gun ownership does not increase safety, and the prevalence of guns directly correlates with significantly greater risk of gun-related homicides and suicides. While the facts surrounding the safety of having a gun in the home are clear, the choice to own a gun is more complicated for many homeowners.
What happens when you use a gun in self-defense?
After a self-defense shooting, you will be interacting with law enforcement. … If you shoot someone and they run away, you need to call 911 immediately. If you draw your gun and they run away, you need to call 911 immediately. If you shoot a home intruder and they are clearly dead, you need to call 911.
Why does a gun recoil backwards when fired?
When a bullet is fired from a gun, the gun exerts a force on the bullet in the forward direction. … The bullet also exerts an equal and opposite force on the gun in the backward direction. Therefore a gun recoils when a bullet is fired from it.
When a gun is fired the momentum of the bullet?
When a bullet is fired from a gun, total momentum before is zero since nothing is moving. After firing the bullet there is a momentum in the forward direction.
Is the recoil of a gun the same force as the bullet?
Both the bullet and the gun experience the same force but in opposite directions. These two forces are equal and opposite of each other. This opposite force manifests itself as recoil, which is where the gun pushes back whenever it is fired.
Why can a small mass bullet kills a person?
Why can a small mass such as a bullet kill a person when fired from a gun? Answer: It is so because even if the mass of the bullet is small, it moves out of the gun with a very high velocity, due to which the momentum produced is high (p = mv). This high momentum of the bullet kills a person.
Why are nylon ropes favored by mountain climbers physics?
Nylon ropes, which stretch considerably under tension, are favored by mountain climbers because they stretch and take time in coming to a stop when mountain climbers accidentally fall.
Why is it hard to stop a supertanker?
Why is it so difficult to stop or turn a supertanker? A supertanker has an enormous mass so, with any velocity at all, its momentumwill be very large and it will require a force acting over a very long time to bring it to a stop.
When you jump from an elevated position?
When you jump from an elevated position you usually bend your knees upon reaching the ground. By doing this, you make the time of the impact about 10 times as great as for a stiff-legged landing.
Why are padded dashboards safer than hard dashboards?
Padded dashboards are safer than unpadded dashboards because the padded dashboard will increase the time required to stop your head from moving forward during an accident. The increased stopping time results in a smaller force being applied to the person’s head.
When jumping from a significant height Why is it advantageous?
When jumping from a significant height, it is advantageous to land with knees bent because it increases the time taken by person to come to stop, decreases the impact, and hurts less.
