A student begins at rest and then walks north at a speed of v1 = 0.55 m/s. The student then turns south and walks at a speed of v2 = 0.53 m/s. Take north to be the positive direction. If the student travels in the stated directions for 30.0 seconds at speed v1 and for 20.0 seconds at speed v2, what is the net displacement, in meters, during the trip? If it takes the student 5.0 s to reach the speed v1 from rest, what is the magnitude of the student’s average acceleration, in meters per second squared, during that time?

A student begins at rest and then walks north at a speed of v₁ = 0.55 m/s. The student then turns south and walks at a speed of v₂ = 0.53 m/s. Take north to be the positive direction.

If the student travels in the stated directions for 30.0 seconds at speed v₁ and for 20.0 seconds at speed v₂, what is the net displacement, in meters, during the trip?

If it takes the student 5.0 s to reach the speed v₁ from rest, what is the magnitude of the student’s average acceleration, in meters per second squared, during that time?
