Sledge hammer physics, impact momentum

AI Thread Summary
To determine the impact velocity of a sledge hammer striking rubber, one can calculate the potential energy at the height of 8 feet and convert it to kinetic energy at the moment of impact. The velocity just before contact can be derived from this energy conversion. Additionally, the resilience of rubber affects how much energy is absorbed and how fast the hammer rebounds after impact. Researching the specific resilience values for rubber will provide more accurate calculations for the hammer's exit velocity. Understanding these physics principles is crucial for accurate assessments in practical applications.

I need to find reasonable numbers for acceleration of a sledge hammer when striking a mass of rubber? A strong man can raise the hammer to 8 ft, then brings it down hard. What is reasonable velocity of the hammer before it contacts the mass of rubber? How much resilience is there, what is the velocity of the hammer as it leaves the rubber?

Thanks

You can find in theory the velocity of impact by equation the potential energy of the hammer to the kinetic energy at the moment of impact.

The resilience you might need to look up for rubber.
 

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
