AI Thread Summary
In a projectile launched at an angle, the vertical velocity just before landing will be equal in magnitude to the initial vertical velocity, but the direction will be reversed, assuming the landing height matches the launch height. The angle of the projectile just before landing will have the same magnitude as the initial launch angle, but it will be directed below the horizontal instead of above. This confirms that both the vertical speed and angle maintain consistent relationships throughout the projectile's flight. Understanding these principles is crucial for analyzing projectile motion effectively. The discussion highlights the importance of direction in velocity and angle in projectile dynamics.

Just wanted to confirm: in a projectile launched at an angle if you know the intital velocity In the vertical direction , will the velocity in the y direction just before it lands be the same?
Also the angle just before it lands will be the same as the intital angle, right?

The vertical speed will be the same, but the direction will be reversed. (Assuming the landing point is the same height as the launch point.)

Also the angle just before it lands will be the same as the intital angle, right?
The magnitude of the angle will be the same, but one will be above the horizontal and the other below.
 

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?
