WebDec 14, 2014 · You need to integrate acceleration to get the velocity. v ( t) = ∫ t = 0 t a. d t. There are a number of ways of doing this numerically. I assume that you get these readings regularly with a spacing of δ t, for example δ t = 100 m s or something like that. About the simplest way to do it is. v ( t) = v ( 0) + ∑ a × δ t. WebFeb 2, 2024 · All you need to know is that speed is expressed in feet per second (imperial/US system) or in meters per second (SI system) and time in seconds. …

WebThe change in speed at t = 6 would be the derivative of the curve at that point, but since the curve has a sharp point in t = 6, the derivative is undefined. That's because on the left side, the slope is getting more and more negative. Even infinitesimally close to … Webpi = m1vi1. After the hit, the players tangle up and move with the same final velocity. Therefore, the final momentum, pf, must equal the combined mass of the two players multiplied by their final velocity, ( m1 + m2) vf, which gives you the following equation: ( m1 + m2) vf = m1vi1. Solving for vf gives you the equation for their final velocity:
