The position function of an object moving horizontally along a straight line as a function of time is s(t) = t^2 -3t +2, t≥0, in metres, at time t, in seconds.
a) Determine the speed of the object when the position is 0.
answer: 1 m/s
Isn't the answer 1 m/s AND -1m/s? That's what I get when I plug in t=2 and t=1 in the function
b) When does the object move to the left?
answer: between 0s and 1.5s
Does between mean that it includes the value? since the question states that t≥0, shouldn't the answer be 0≤t<(3/2)?
