1. A small plane leaves Toronto and flies 80 km [west] to Hamilton. The Hamilton airport is crowded, so the plane is advised to land at Guelph, 20 km [north]. The Toronto-Hamilton trip takes 20 minutes and the Hamilton-Guelph trip takes 8 minutes.
(A) What is the total distance travelled by the airplane?
Answer: m/s2
(B) What is the total displacement?
Answer: m/s2
(C) What is the speed for the entire trip?
Answer: m/s2
(D) What is the velocity for the Toronto-Hamilton leg of the trip.
Answer: m/s2
2. A boy runs out the door and starts down the road for school at 10 km/hr. Six minutes later, his mother discovers that he has forgotten his lunch and she runs after him at 14 km/hr.
(A) How far does he get in 6.0 minutes?
Answer: m/s2
(B) How long (in seconds) does it take her to catch him?
Answer: m/s2
(C) How far from home is he when she catches him?
Answer: m/s2
3. A car starts at a displacement of 0 m and 0 seconds, travels forward at 5 m/s for 3 seconds, then stops for 2 seconds, then travels in reverse at 3 m/s for 6 seconds.

3. A plane is moving along at a uniform air speed of 325 km/hr (relative to the air.) The instruments also show that the heading is south [300]west. (direction of plane with respect to air) The wind velocity is 80 km/hr [west]. What is the velocity of the plane relative to the ground?
Answer: m/s2
4. Student AA@ wants to toss a ball directly upwards to Student AB@ who is leaning out a window directly above him. The ball is thrown upwards with a velocity of 8.0 m/s. Student AB@ is 4.0 meters above student AA@. Acceleration due to gravity is 9.8 m/s2 [down].
How long was the book in the air?
Answer: m/s2
5. A mouse is crawling inside a cart which is being pushed across the deck of a moving boat. The mouse is moving at 0.5 m/s[east] relative to the cart. The cart is travelling at 1.2 m/s[east] relative to the surface of the boat, and the boat is moving at 4.0 m/s north[300] west relative to the water. What is the velocity of the mouse relative to the water?
Answer: m/s2
6. A car travels at 100 km/hr [N] when it goes around a curve in 10 seconds, ending up with a final velocity of 100 km/hr [W]. What is the car’s acceleration?
Answer: m/s2
