Initial Initial velocity Theoretical Velocity

AI Thread Summary

To calculate the theoretical initial velocity for a projectile, the key parameters include the target distance of 25.6 meters, an initial velocity of 16 m/s, and a time of 2.6 seconds. The range of the projectile is noted as 26.7 meters, assuming no air resistance. The discussion suggests that the problem resembles a typical homework question in physics. Participants are encouraged to provide assistance using relevant equations. The conversation emphasizes the importance of understanding the underlying physics principles for accurate calculations.

I can do with just an equation, but if anyone is willing to help:
Target is 25.6 m away from canon
Initial Velocity = 16 m/s
Time = 2.6 s
Range = 26.7m
No air resistance

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 '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 '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?
