Grade 10 IB Students!
If you need some pretest help, I will be available in room 209 during the lunch period on Monday, October 16.

(A) 150 m [forward] (B) 150 m [forward] (C) 100 m [forward] (D) 350 m [forward] (E) 400 m [forward]
INTERVAL A: 15 m/s [forward]
INTERVAL B: 0 m/s
INTERVAL C: 5.0 m/s or 5.0 m/s [back]
INTERVAL D: 20 m/s [forward]
INTERVAL E: 10 m/s [forward]
 (displacements)
(A) 150 m [forward] (B) 100 m [back] (C) 400 m [forward]
(distances) (A) 150 m (B) 200 m (C) 500 m
 2.5 m/s^{2}
These answers are relating to the vt graph question.
(A) 20 km/hr, 40 km/hr, 80km/hr
(B) 10 km/hr/s, 6.7 km/hr/s, 0 (you won't see km/hr/s as a unit of acceleration on your test)
 all these displacements are [forward]:
240 km, 270 m, 18 m, 338 m
 0.20 m/s^{2}
 (A) 40 m/s (B) 800 m [forward]
 10 m/s [south]
 12 m/s [north]
