The velocity as a function of time for an object moving in a straight line.

The graph in front of you shows the velocity v as a function of time t for an object moving in a straight line. Use the graph to answer the following questions, if it is known that an initial position is +50 m.
v_t1
a) For each of the three sections of the movement, write the position of the object as a function of time.
b) How long will it take for the object to pass the origin of the x axis?
c) What is an average velocity of the object during the first 30 s?
d) What are distance, displacement and position of the object after the first 30 s?
