An object is moving along a straight line. The graph shows the object's position from the starting point as a function of time.

a) In which segment(s) of the graph does the object's average velocity(measured from t = 0 s) decrease with time?

b) What was the instantaneous velocity of the object at t = 4 s?

c) In which segments(s) of the graph does the object have the highest speed?

d) At which time(s) does the object reverse its direction of motion?

The velocity of an object in linear motion is given in terms ofa stop watch reading by the formula:
v=(12.5 m/s2)t - (5.0 m/s3)t^2.

a. What is the object's acceleration at t=0.50 s?

b. If the object was at the origin at t=0, where is it locatedrelative to the origin at t=0.50 s?
