Question

A particle starts from rest at the point two units from the origin and moves along a flat track with a constant positive acceleration for time t > or = 0. Which of the following could be the graph of the position s(t) of the particle relative to the origin as a function of time t? and why????

Answer 1

Use the formulas eg v= u + at, s=ut + at^2/2 to estimate the graph

Answer 2

I dont even know what those formulas are...

Answer 3

OK. forget the math, just think about it.

Assume distance is represented along the horizontal axis and time vertical, where is the particle at time t = 0?

Answer 4

It is ?

Answer 5

I mean is it?? *

Answer 6

am i right or wrong?
