Unformatted text preview: 1.40 Corrections First picture was drawn of person throwing ball in the air 2 meters above ground. The student labeled velocity correctly at 15 m/s and initial time of 0. Student then drew top part of picture labeling velocity equal to zero which is correct but forgot to label acceleration to 9.8 m/s2. Final variables such as velocity and height are labeled correctly by both equaling zero. Motion diagram is also done correctly, with the upward motion velocity vectors getting smaller as they go up (due to acceleration of gravity), then, in downward motion, velocity vectors get larger, also due to acceleration of gravity. Problem is done mostly correctly and it is noticeable that student put effort, thus student should receive full credit. ...
