A cyclist completes a 100km race in 2:25:30. The race course proceeded 50km north, then 25km east, then 25km south. Her split times were 1:06:05 at the 50 km point and 1:49:19 at the 75kmpoint.

1. What is her average velocity from start to finish (both in direction and magnitude)?

2. What is her displacement from start to finish (both direction and magnitude)? Draw this to the diagram.

3. At the start for the race the cyclist accelerates from 0 to 15 m/s (north) in 7sec. What is her average acceleration (both in magnitude and direction)?
