4. A turtle starts from rest and moves with a constant acceleration along straight ditch. He starts his stopwatch as he passes a fence post and notes that it takes him 10 s to reach a pine tree 10 m farther along the ditch. As he passes the pine tree, his speed is 1.2 m/s. a) What was his velocity when he passed the fence post? [3 marks] b) How far was he from the fence post when he started from rest? [5 marks] 4.
