4) average travel speed 平均行程速度 1. It is concluded by the analyses of the average travel speed according to different drivers that: drivers with choleric temperament are full of adventure and drive the most quickly with the high latent occurrence of traffic accident; while the melancholic....
An illustration of the difference between average and instantaneous rates of changeThe graph off(t) shows the secant between (t,f(t)) and (t+h,f(t+h)) and the tangent tof(t) att. As the time intervalhapproaches zero, the secant (average speed) approaches the tangent (actual, or ins...
An object moves along the x axis according to the equation x(t) = (2.70t2 - 2.00t + 3.00) m.(a) Determine the average speed between t = 1.70 s and t = 2.90 s.(b) Determine the instantaneous speed at t = 1.70 s and at t = 2.90 s.(c) Determine the aver
. With the definition of average velocity as the distance per time, the body’s average velocity over an interval fromttot+his given by the expression [g(t+h)2/2 −gt2/2]/h. This simplifies togt+gh/2 and is called thedifference quotient of thefunctiongt2/2. Ashapproaches 0, this...
Say you need to drive a distance of 800 miles and your average rate of speed is 60 miles per hour, can you find out how long it will take to get there? Yes you can! You just plug in the values that are known and solve for the variable that is unknown. d=rt(800)=(60)t80060...

There are certain devices we can use to accelerate the computation which enable us to obtain the solution of a kinetic equation by the Monte Carlo method, even on machines of average speed, to considerably greater accuracy than the use of other known methods. As an example of such a ...
The International Space Station travels at an average speed of 28,000 km/h or 17,500 mph. In a single day, the ISS can make several complete revolutions as it circumnavigates the globe in just 90 minutes. Placed in orbit at an altitude of 350 km, the station is visible to the naked...
