1/2a(3.4)^2+[3.4a(a=0)](6.6)=100
[] is Vi and a in this case is 0 at it stops to accelerate when it gets to 3.4s
so a=100/(.5)(3.4)^2....=17.30
now Vf=(3.4*17.30)+17.30(6.6)...=173.01
Using the information in the question, of course he can!
You haven't specified what magnitude of acceleration he can maintain for 3.4 seconds, so the
whole effort is a piece-o'-cake, and anybody who can accelerate for 3.4 seconds can do it.
For example, since you've imposed no restrictions on the magnitude of acceleration, let's
assume that he accelerates for 3.4 seconds at the rate of 17.3 meters per second-squared,
to a maximum speed of 58.8 meters per second. His average speed during that time is
58.8/2 = 29.4 meters per second, and at that average speed, he covers exactly 100 meters
in 3.4 seconds ... crossing the finish-line and shattering all past and future world records
just as he reaches his top speed and stops accelerating.
On the other hand, if he had a rough night, and all he really wants to do is finish 100 meters
in 10 seconds and go lie down, then he need only accelerate at a leisurely 2 meters per second-
squared for 10 seconds, reaching the top speed of 20 meters per second. Then his average speed
is 10 meters per second, putting him at the 100-meters mark after 10 seconds.
plagioclimax is when the humans have influenced the vegetation so that is prevents it from reaching it climatic climax
when the light reaching their eyes is not the same on the both side
It depends on the species. Queen Alexandra's Birdwing butterfly is the largest butterfly in the world with the female reaching a wingspan of 31 cm.
Where a cell goes into a state of neither dividing nor preparing to divide, some cells stay in G0 stage once reaching maturity.
Because in a coniferouse forest the trees prevent sunlight from reaching the ground
An object falling from a tall building would accelerate at a rate of 9.807 m/s2 until it reached terminal velocity, at which point it would not accelerate until it impacted the ground. Its velocity would increase as it fell until reaching terminal velocity, and then 0 when it hit the ground.
None. Assuming they are falling with the same conditions, they accelerate equally. But the 200 gram object has the greatest terminal velocity therefore reaching a higher velocity before resting at a constant speed.
No. The acceleration is a constant 9.8 m/s2 down the whole time because acceleration depends on the net force and the Earth did not change its pull.
The speed or velocity of a train has no bearing on its acceleration.
increase- your speed will increase until terminal velocity is reached. From there it will stay constant.
The speed of an object falling towards the earth will increase because the gravitational force on the object will accelerate it at a rate of 9.8 m/s² (32.2 ft/sec2). So the speed of a falling body can be calculated by the simple formula: v=u+at Where v = current vertical speed u = vertical speed when it began to fall a = acceleration t = time since it began to fall All of this describes how gravity works. If an object doesn't behave according to this description, the reason is that it's falling through air, which tries to slow it down. (Think of a parachute.) Where there is no air, falling objects behave exactly this way. Notice that the mass or weight of the object doesn't appear anywhere in the math. Where there is no air, all objects, no matter what they weigh, including feathers, rocks, airplanes, sheets of paper, and parachutes, fall with the same acceleration, and every object that falls from the same height hits the ground at the same speed.
because it is being regulated.
Ion product constant is essentially when something reaches equilibrium. Such as in the case of water. When water reaches its ion product constant it becomes both a base and an acid, reaching equilibrium.
Realized strategies are behaviors or actions that stay constant as time goes on. This usually leads to it reaching its intended solution.
Of course. You need to go back and review the definitions of those terms. Acceleration is the rate at which velocity changes. If velocity is not changing, then there is no acceleration. But the velocity doesn't have to be zero just because it's not changing. Velocity is the speed of an object and the direction in which it's moving. If it's moving at a constant speed in a straight line, then it has plenty of velocity. But since the speed isn't changing and the direction isn't changing, there's no acceleration. If acceleration comes along somehow ... such as by igniting a rocket motor, or gravity pulling the object downward, or someone reaching out and giving the object a push, then the speed or direction may change, and that'll be a change of velocity.
It is accelerating at 1.2m/s per second.
Without an outside frame of reference, there is no way to distinguish a force caused by gravity from a force caused by acceleration. With sufficient fuel (or a propulsion system that did not require reaction mass) it would be possible to accelerate at the rate of 32 feet per second per second (or 9.8 meters per second per second) and feel the same force on your body or on your instruments as is caused by living on the surface of the Earth. Of course, such a spacecraft would be capable of reaching the Moon in an hour, reaching Mars within a day or two, and reaching Pluto in less than a month. (Less, if we don't have to spend half our time accelerating and the other half DEcelererating so that we would be stopped with reference to the destination planet.)
