    Determine the Magnitude of the instantaneous Velocity

    I took calc and calc 2 about 4 years ago, I passed with A's but left school on military orders and have just gotten back into school. I forgot a lot of what I learned then.

    Determine the Magnitude of the instantaneous Velocity

    Homework Statement Determine the Magnitude of the instantaneous velocity at T=5s Function is x=AT^2 + B A=2.1m/s^2 B=2.8 M Homework Equations The previous questions answered on this problem are: AVG Velocity is 16.8 Displacement is 33.6 from 3s to 5s The Attempt at a Solution I'm not sure how...

    Finding Velocity from Position: How to Use Limits

    I found another problem worked out on this website, so what I did was 6(2.5+Δt)(2.5+Δt) to get 6Δt^2 + 30Δt + 37.5, this equation is x + Δx, so I have to remove the original x of 37.5, leaving me with Δx = 6Δt^2 + 30Δt. take this and put it over Δt to get 6Δt + 30, and plug in 0 for Δt because...

    Finding Velocity from Position: How to Use Limits

    Homework Statement The position of a particle moving along the x axis varies in time according to the expression x = 6t2, where x is in meters and t is in seconds. Evaluate its position at the following times. (a) t=2.5s (b) t=2.5s + Δt (c) Evaluate the limit of Δx/Δt as Δt approaches zero to...
