Practice Question 2 (a) A student walks 3.0 m [N] and 5.0 m [N37.E]. The magnitude of 3.0 m her displacement is: C. 7.6 m 5.0 m Break the 5.0 m [N37.E] vector into components: 4.0 m [N] 4.0 m 3.0 m [E] 370 |Ad =(3.0+4.0m)+(3.0m)-=7.6m 7.6 m (b) The direction of her displacement is: 230 1 3.0 m B. N23.E 3.0 m tan =230 3.0 m +4.0m
