There are three phases to this calculation:
# The initial powered acceleration # The deceleration under gravity to the top of the trajectory # The acceleration under gravity back to the ground Using the equations:
a = 2(s - ut)/t2
a=(v-vo)/t
Phase 1
Acceleration (a) = 35m/s2
Time (t1) = 35s
Velocity(v) = 35 x 35 = 1,225m/s
Distance travelled (S1) = 21,437m
Phase 2
Acceleration (a) = -9.8m/s2
Initial Velocity (Vo) = 1,225m/s
Distance travelled (S2) = 76,562m
Time (t2) = 125s
Phase 3
Acceleration (a) = 9.8m/s2
Distance Travelled (St) = S1 + S2 = 98,000m
Time (t3) = 141.4s
Thus total time = t1 + t2 + t3 = 35 + 125 + 141.4 = 301.4s
... and what is the question? The second ball should arrive at the floor a second after the first, both should have the same speed.
if you ignore air resistance, it would take about 3.5 seconds; at ttat point where it hits the ground it is traveling at 75 mph. Because of the air drag, it may take a bit longer to hit the ground.
Not sure what a strait line is! Five people can stand in a straight line, with Jessie third in 24 ways if you ignore left-to-right and right-to-left "reflections".
50m/s. The kinetic energy (movement energy) of the ball when it leaves the gun is gradually converted into gravitational potential energy as it moves up and slows down. Eventually it reaches its highest point and stops. It has zero kinetic energy, all the energy has been converted into gravitational potential. The ball then starts to fall under gravity. The gravitational potential energy is converted back into kinetic energy. No energy is lost so the ball arrives back where it started with the same kinetic energy it left with or to put it another way at the same speed it left. If you do not ignore air resistance it arrives back a bit slower and the physics gets much much more complicated..........
they ignore it. because they are stupid
Bussinesses tend to view the effects of their activities as negligible and ignore them
-- There is no formula for the object. -- If you can ignore the effects of air resistance, then there are formulas for the object's height, speed, acceleration, time spent falling before reaching a certain height, and time spent falling before reaching a certain speed. All of the formulas are different. -- If you can't ignore the effects of air resistance, then there are different formulas for each of those quantities. But the formulas involve the size, shape, weight, and surface composition of the object, and each formula is several lines long.
Not if you can ignore air resistance, it doesn't.

Yes - but only if you can ignore air resistance, that is, if the objects fall for a sufficiently short time, and have a sufficiently high mass, and sufficiently small surface area, so that air resistance becomes insignificant.Yes - but only if you can ignore air resistance, that is, if the objects fall for a sufficiently short time, and have a sufficiently high mass, and sufficiently small surface area, so that air resistance becomes insignificant.Yes - but only if you can ignore air resistance, that is, if the objects fall for a sufficiently short time, and have a sufficiently high mass, and sufficiently small surface area, so that air resistance becomes insignificant.Yes - but only if you can ignore air resistance, that is, if the objects fall for a sufficiently short time, and have a sufficiently high mass, and sufficiently small surface area, so that air resistance becomes insignificant.
If you ignore air resistance, then they will reach their maximum height at the same time. In order not to ignore air resistance, you would need to know their shapes.
If you ignore air resistance, weight has no effect at all.
no i dont think so,normally when someone is mad they just ignore you. your straight
A strictly structured change process often ignores the ingrained human resistance to change.
Leakage resistance in any circuit is resistance less than infinity where it is not expected, such as across an insulator. In the ideal sense, all circuits have leakage resistance because no insulator is perfect, but we usually ignore this except in special situations because it does not normally matter in real applications. In an RC circuit, leakage resistance would most typically be across the capacitor.
