A student begins at rest and then walks north with an average speed of v1=0.85 m/s. The student then turns south and walks with an average speed of v2=0.74 m/s.

1.) What was the student's overall average velocity, in m/s, for the trip assuming the student spent equal times at speeds v1 and v2?

2.) if the student traveled for 30 seconds at speed v1, and for 20 seconds at speed v2, what was the net displacement (in meters) during the trip?

3.) Assuming that it took the student t= 5 seconds to reach the average speed v1 from rest, what was the students average acceleration magnitude, acceleration average in m/s2, during this time?
