AI Thread Summary
A block is projected up a frictionless inclined plane at a 35-degree angle with an initial velocity of 8.2 ft/s. To determine how far the block travels up the incline, the time taken to reach that point, and its speed upon returning to the bottom, conservation of mechanical energy is applied. The discussion emphasizes the importance of using energy principles rather than kinematics for solving the problem. Participants are encouraged to focus on the mechanics involved without duplicating questions across forums. The thread is a resource for understanding the application of energy conservation in physics problems.

a block is projected up a frictionless inclined plane. the angle of incline is 35 degrees, and the initial velocity is 8.2 ft/s. how far up the plane does the block travel? how long does it take to get there? and what is its speed when it gets back to the bottom?

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?

Thread 'Free fall of person in a sled to direct horizontal motion by atmospheric resistance'

Let there be a person in a not yet optimally designed sled at h meters in height. Let this sled free fall but user can steer by tilting their body weight in the sled or by optimal sled shape design point it in some horizontal direction where it is wanted to go - in any horizontal direction but once picked fixed. How to calculate horizontal distance d achievable as function of height h. Thus what is f(h) = d. Put another way, imagine a helicopter rises to a height h, but then shuts off all...
