I have a question that i dont know where to start

An object its travelling along the x-axis so that its speed is given by

v(t)=t^2 -7t +10 m/s

A) find the times when the object is at rest.

B)Find the acceleration at both of these times. Interperate the acceleration in terms of the motion of the object.

C) if the object its at x=0m at t=1, find the position of the object at time t.

D)find the leftmost position of the object for all t>or=0

Any help would be great to push me in the right direction

Thanks

Jimmy
