Displacement What’s your vector Victor?

A student travels 2 km [E] and then goes 5 km [W]. What is the displacement? 1 cm = 1 km (create a scale) mathematically… [E] = +ve d 1 = +2 km d 2 = -5 km 2 km [E] 5 km [W] 3 km [W] (include compass heading) (draw 1 st vector) (draw 2 nd vector) (draw resultant vector)

A student rides her bike from her house to school. The path she takes is 2km long but the displacement is 1 km [E]. It takes her 30 minutes. Calculate her speed and velocity. = 4 km/h = 2 km/h [E] speedvelocity

Proper Form for Word Problems G-given information (right hand margin) R-required information(right hand margin) A-appropriate formula S -substitute S- solve S-statement (significant digits and units)

1.A cyclist travels 16.0 km [N] and then heads 24.0 km [S] in a time of 2.1 hours. Calculate her average velocity.  the velocity of the cyclist was 3.8 km/h [S]

2.A person jogs at a speed of 3.2 m/s for 25 minutes. What distance did the person travel? v = 3.2 m/s t = 25 min. = 25 x 60 = 1500 s d = ?  the distance travelled was 4800 m.

3.How much time will it take for a car to travel 2.3 km [W] at a velocity of 42.0 m/s[W]?  the time was 55 s. 1.2 Prac. #5-9 UC #3-6
