What is a hammer of mass 500 grams moving at 50 meters per second strikes a nail?
What is a hammer of mass 500 grams moving at 50 meters per second strikes a nail?
Force of the nail on hammer, |F|=|ΔP|t=250.01=2500 N. Was this answer helpful? A hammer of mass 500 g, moving at 50 ms−1, strikes a nail. The nail stops the hammer in a very short time of 0.01 s.
What is the force of the nail on the hammer?
The force of nail on the hammer. F=Change in momentum of hammerTime. F=m(v−u)t=0.5(0−50)0.01=−2500N. Negative sign denotes that the force of nail on the hammer is acting in the direction opposite to that of motion of hammer.
How much mass is in a hammer?
Framing hammer: 20 ounces to 32 ounces. Sledgehammer: 6 pounds to 20 pounds. Ball-peen hammer: 8 ounces to 32 ounces. Brick hammer: 2 pounds to 4 pounds.
What is the velocity of a hammer of mass of 1kg falls freely from height of 2 m?
= 6.32 m/sec.
How much force is a hammer?
For example, if a 5 pound hammer is swung at 50 feet per second, then the kinetic energy of the hammer is 5 * 50 * 50 / 64.32 = 194 foot pounds. If this then compresses a forging by 1/8 of an inch, then neglecting rebound, then it is about 194 * 96 or about 18,600 pounds of force on average.
Does a hammer increase force?
Now, force is the rate of change of momentum. The hammer is heavier so momentum is more initially even if hand and hammer hit at same velocity. As well as the time taken for the momentum to change to zero is less in case of the hammer. Both these factors increases the force exerted by the hammer considerably.
Is hammer pushes a nail a balanced force?
The hammer striking the nail represents unbalanced forces. The hammer strikes the nail with a strong downward force. The downward force of the hammer is greater than the force of the wood pushing up on the nail.
Who invented hammer?
The hammer was one of early man’s first tools, and has existed since the Prehistoric Period, around 3.3 million years old. No one is exactly sure who the individual was who came up with the idea, but its creation was most likely the result of necessity and survival.
What is the physics of a hammer?
A hammer is a simple force amplifier that works by converting mechanical work into kinetic energy and back. In the swing that precedes each blow, the hammer head stores a certain amount of kinetic energy—equal to the length D of the swing times the force f produced by the muscles of the arm and by gravity.
How heavy is a hammer in KG?
The head mass is usually 1 to 9 kilograms (2.2 to 19.8 lb). Modern heavy duty sledgehammers come with 10-to-20-pound (4.5–9.1 kg) heads. Sledgehammers usually require two hands and a swinging motion involving the entire torso, in contrast to smaller hammers used for driving in nails.
Why do we use a heavy hammer to drive a nail deeper into wood?
The hammer is heavier so momentum is more initially even if hand and hammer hit at same velocity. As well as the time taken for the momentum to change to zero is less in case of the hammer. Both these factors increases the force exerted by the hammer considerably. Hence, it is able to drive a nail inside a wall.
How much work is needed to be done on a ball of mass 50 gram to give it momentum of 5 kg metre per second?
So, work done = Change in KE of the ball =12mv2=12×0.05×1002=250 J. Q. A body of mass m is travelling with velocity v.
How many Newtons is a hammer strike?
When the hammer hits the nail it transfers this energy to the nail in order to move it 1cm (0.01m). A transfer of energy is known as work done and work done = force x distance. So, force = work done / distance = 25 / 0.01 = 2500N Answer: Average force = 2500 Newtons.
How do you calculate the energy of a hammer?
- Step 1: Given. Mass, Height, Step 2: Formula used. …
- Step 2: Formula used. Potential Energy, Where m is mass, g is the acceleration due to gravity, and h is the height. Step 3: Calculation. …
- Step 3: Calculation. By substituting the values in the above formula, we get. PE = 10 kg × 9 . 8 ms – 2 × 10 m PE = 980 J.
