Gravity pulls at an object at 16 ft/sec.
If I throw an object vertically, as in straight up into the air with no curve at all, gravity will pull on it at 16 ft/sec

But if I throw an object in an arc, or in between a vertical and horizontal path, shouldn't gravity pull on it at 8ft/sec?

If a 70.3 kg person eats one 40.9 g brownie with nuts, how many minutes would it take for the person to walk off all the calories in the one brownie ? Walking requires energy equal to 2.5 times the basal metabolic rate.

Do NOT consider the energy needed to digest, absorb, and metabolize the snack itself, which the text describes as 10% of the ingested amount of food. Use the total amount of the energy in the one brownie in your calculation.

Breaking my brain to figure this one out:

A 2.00g sample of an unknown metal, M, was completely burned in excess O2 to yield 0.02224 mol of the metal oxide M2O2, what is the unknown metal?

So far, I've run in circles and only managed to figure out that the reaction would have to be something like 4M+3O2--> 2M2O3 any hints as to how to begin solving this would be greatly appreciated.

I have been saying for years that our "Local Spatial Field" is actually warped due to a nebula event that created our "Local Compression Bubble" that has been detected in our sector of the Galaxy. This infers that the space field is folded and stars that we "perceive" at certain distances are in reality merely "perceived distance" and not the "actual distance", which I propose is a "variable distance" going from greatest apogee to lesser apogee. My concern is that our Solar System may be on a collision course with another star system, and this has totally eluded the entire scientific community. I conjecture this is why the ecosystem and climate of the Earth is heating up, due to an approaching extra-solar star system that will penetrate through our Solar System, precipitating an extinction level event and wiping away all traces of our global technoculture and catapulting the post-catastrophic survivors back to a state of Neobarbarism reactivating the slow process of recivilization.
