Question

a jet engine moves along an expiremental track (which we call the x axis) we will treat the engine as if it were a particle. its position as a function of time is given by the equation x=At²+B, where capitol A = 2.10m/s² + B=2.80m.
-determine the displacement of the engine during the time interval from t1 = 3.00s to t2 = 5.00s

any help is good thanx

Answer 1

Just plug in t = 3, 4 and 5 seconds into the equation
x = 2.10 t^2 + 2.80
and compute x for each value.

They may expect you to fill out a table with more t values or draw a graph. Is that all there is to the problem?

Answer 2

nope that's all there is for this question.....how exactly do you compute x for each value??

Answer 3

Use the formula you were given.
