An object is moving along a horizontal line modelling the position function
s(t)=t^(2)-10t;0<=t<=12,, where s is in metres and t is in seconds.
a) what is the initial position of the object?
b) when is the particle at rest?
c) when is the object travelling left of the origin? when is it travelling right?
d) what is the initial velocity?
e) what is the acceleration ? What does this mean?
f) determine the total distance travelled by the particle? (Draw a diagram similar to the
examples in the lesson).
