at the Canadian Men's National Team keeper. He runs 27.0 m [N 30⁰ W] in 5.55 s and then changes direction to cover 63.0 m [ E 11⁰ N ] in 12.60 s before being tackled by security. For the displacement you may solve using any method (scale diagram, trig, or components) - in all cases you must include a labeled vector sketch.

Determine:

a) the average speed

b) the average velocity (a one-sixth scale works well)

5. A boat going at 15 km/h [N] accelerates to 55 km/h [N] covering 200 m [N] in the process.

How long does this take in seconds?

6.a) Can an object be accelerating south but moving north?? Explain.

b) Can an object be undergoing acceleration but have a velocity of zero?? Explain.
