WebAt time equals 2 and 4 seconds, we can't find the instantaneous velocity/ speed because it's not differentiable at those two points. I understand that mathematically, but I'm sort of struggling to grasp that idea intuitively. So, the concept of an instantaneous velocity is basically the derivative of the curve at a certain point right? Web1. (a) Calculate Earth’s average speed relative to the Sun.

WebFeb 21, 2015 · The difference between speed and velocity is that speed is a scalar, while velocity is a vector. In the 1D case, this changes to speed being the absolute value of velocity. Let us now compute the arc length: $$\int_0^3 \sqrt{1+(10(1-t))^2}dt$$ $$\int_0^3 \sqrt{1+100(1-2t+t^2)}dt$$ $$\int_0^3 \sqrt{100t^2-200t+101}dt$$ Notice how hard this ... WebThe instantaneous speed of an object is then the magnitude of its instantaneous velocity. v = v Speed tells you how fast. Velocity tells you how fast and in what direction. units. … WebYes, instead of multiplying by time you can just plug the numbers into the equation: time = distance / rate (speed). In this case it would be: time = 720m / 3m per sec When you divide 720m by 3m/s the meters cancels out and you are then left with time which would be 240 seconds. This equation though is just a manipulation of rate = distance/time. the ups store 85042
