![]() ![]() You can calculate the escape velocity by looking at the conservation of energy. Since the gravitational force decreases with distance, it actually turns out that there is a certain speed you can throw the ball such that it will never return, never. Taking that into account, it will actually reach a height of 934 km. is a New York Domestic Business Corporation filed On August 8, 2000. Actually, as the ball gets farther from the center of the Earth, the gravitational force decreases. That assumes the gravitational force has a constant value. So what if I throw it really fast, with an initial velocity of 4,000 m/s (9,000 mph)? If I ignore air resistance, and I ignore why I'm throwing this ball up instead of pitching in the majors, I calculate that it’ll reach a height of 816 kilometers. The faster I throw it, the higher it goes. If I double the initial velocity, it will go 20 meters before falling down. ![]() With this speed, that max height would be 5 meters. It will eventually get to some maximum height and then fall back down. As it ascends, the ball will slow down because of the downward-pulling gravitational force. Suppose I take a baseball and throw it straight up with an initial speed of 10 meters per second. If it does, I hope they adopt my name of Zoom Spear I.

Oh sure, maybe there is a new way to fly missiles. This is why some of these rockets, like the Saturn V, get so darn big. It's a runaway problem, where carrying more fuel means you need to carry even more fuel. Increasing the mass of the fuel means you need more fuel to push the extra mass. The Trident II is already about 45 feet long this thing would have to be enormous.īut it's even worse than that. This means it would need 289 times more fuel (that's 17 squared), so it would have to be much, much larger. That's a ridiculous amount of energy.Īssuming this Zoom Spear I uses the same kind of fuel as the Trident II, the energy density (energy per unit volume) would also be the same. ![]() Not 17 times as much energy, but 17 2 times more, or 2.8 x 10 13 joules. That's the equivalent of 23 tons of TNT.īut what about Zoom Spear I? If it has the same payload mass but 17 times the speed, it will require much more energy, since the kinetic energy depends on the square of the velocity. Convenient and affordable, these online training sessions provide immediately usable strategies for promoting children’s early language and literacy development in natural contexts and sharing responsive interaction strategies effectively with parents and caregivers.With the listed values, the Trident II payload would need 97 billion joules of energy.
