Oh. Okay. So for the sample; 0 = 20*t + 1/2(-9.8)t^2 0 = 20t + -4.9t^2 0 = 20t - -4.9t^2... ...apply Quadratic Formula at this point?

Equation for air time given velocity? Homework Statement Given a certain velocity going straight up in a vacuum on Earth from y = 0 m, how long does a mass remain in the air? Create an equation. (So, for example, if you throw a baseball up at 20 m/second, how long will it take for it to fall...

Unqualified guess follows. Because, big and energetic as they are, neutron stars have a finite amount of energy too?

Yes, that's wrong- because a single car/photon exhibits wave-like behavior.

I see. So, just to be clear, you CAN know the exact position and momentum of a particle at a single point in the PAST, but NOT the present?

Yes, but you'll know by how much once you take the next measurement. Unless the Uncertainty Principle is only meant to apply to the present, not the past...?

GIVEN: 1. The more accurately you determine a particle's position, the less you know about its momentum, and vice versa. (Heisenberg Uncertainty Principle) 2. Momentum is defined as mass times velocity. 3. Velocity is defined as change in position over time. 4. The rest mass of a particle...
