Homework Statement
The position of a particle moving along the x-axis varies in time according to the expression x = 3t 2, where x is in meters and t is in seconds. Evaluate its position at the following times.
(
a) t = 2.30 s
(b) t = 2.30 s + Δt
(c) Evaluate the limit of Δx/Δt as Δt approaches zero to find the velocity at t = 2.30 s.
m/s
Homework Equations
Listed above.
The Attempt at a Solution
Well for part 'a)', I plugged in the given time (2.30) and got 15.87 meters.
At part 'b)' is where I get stumped. What would you do to find delta t?
Thanks.
