Quick Answer: Why Are Nylon Ropes Favored By Mountain Climbers?

Would you not want to fire a gun that has a bullet that is 10 times as massive as the gun?

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. Firing such a gun in the conventional way would not be a good idea!

Why are the engines of a supertanker normally cut off 25 km from the port?

To bring a supertanker to a stop, its engines are typically cut off about 25km from port. A moving supertanker will have a lot of momentum even when it is moving slowly because it has a lot of mass.

Why is it a serious folly for a bungee jumper to use a steel cable rather than an elastic cord?

Why would it be dangerous mistake for a bungee jumper to use a steel cable instead of an elastic cord. the steel cord will stretch only a little, resulting in a short time of stop and a corresponding large force. The force will be different because the time of extension is different for each of the surfaces.

When starting a heavy train Why will train engineers sometimes back up stop and then proceed forward?

When starting a heavy train, why will train engineers sometimes back up, stop, and then proceed forward? (This technique is called “bunching slack”.) using force from previous start – up in its next back in forth motion to increase velocity, which increases momentum. Two objects, A and B have identical velocities.

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.

How does Dr Hewitt break the piece of wood?

How is Dr. Hewitt able to break a piece of wood in his demonstration? He moves his hand very quickly.

Will you roll backwards if you go through the motions?

Will you roll backward if you go through the motions of throwing the ball but instead hold on to it? If no momentum is imparted to the ball, no oppositely directed momentum will be imparted to the thrower. Going through the motions of throwing has no net effect.

Why is a punch more forceful with?

Why is a punch more forceful with a bare fist than with a boxing glove? A bare fist cannot compress as much as a boxing glove. When a bare fist punches, it quickly stops against whatever it’s hitting, giving it a lot of force. The force of gravity pulls the ball down and changes its momentum.

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.

Why does a baseball catcher’s mitt have more padding than a conventional glove quizlet?

Why does a baseball catcher’s mitt have more padding than a conventional glove? The additional padding in a catcher’s mitt is too increase the time of impact. When a ball is caught, the padding in the mitt is compressed, increasing the time of impact and reducing the force of impact from the baseball.

When you catch a fast moving baseball with your bare hand it is a good idea to?

Why is it a good idea to have your hand extended forward when you are getting ready to catch a fast – moving baseball with your bare hand? An extended hand can move a greater distance when the ball is caught. The greater distance is accompanied by a longer time, which results in less force. 9.

What happens the first time Dr Hewitt lifts the bowling ball near his teeth and lets go?

Why does the bowling ball behave the way it does the first time Dr. Hewitt lifts the bowling ball near his teeth and lets go? All of the initial energy of the ball was converted completely back to potential energy when the ball returned.

Why do mountain climbers use nylon ropes which stretch considerably under stress to catch them if they fall?

Ex 6.5 In terms of impulse and momentum, why are nylon ropes, which stretch considerably under stress, favored by mountain climbers? As nylon ropes stretch, they exert a force over a greater time so that force will be smaller than with a hemp rope which exerts a force over a shorter time.

What would happen if you fire a gun that has bullet ten times as massive as the gun?

No, because the recoil speed of the gun will be ten times higher, so it will be better to throw the gun than fire the bullet.

Which has the greater change in momentum a 50 gram clay ball that strikes a wall at 1 m/s and sticks or a 50 gram super ball that strikes a wall at 1 m/s and bounces away from the wall at 0.8 m s?

Which has the greater change in momentum, a 50 gram clay ball that strikes a wall at 1 m / s and sticks or a 50 gram superball that strikes a wall at 1 m / s and bounces away from the wall at 8.0 m / s? Explain? The ball that bounces has a GREATER change in momentum being that the numerical value is larger.
