Instantaneous velocity calculus example
Nettet12. sep. 2024 · Average acceleration is the rate at which velocity changes: (3.4.1) a ¯ = Δ v Δ t = v f − v 0 t f − t 0, where a ¯ is average acceleration, v is velocity, and t is time. (The bar over the a means average acceleration.) Because acceleration is velocity in meters divided by time in seconds, the SI units for acceleration are often ... NettetYou want to estimate the instantaneous velocity at t = 3. It would be best to use the points with t = 2 and t = 4. The approximation for the instantaneous velocity is just the slope of the line segment connecting the two points (no need to find the equation of the tangent line). Note that slope is just the average velocity of s over [ 2, 4].
