a. FIGURE EX1.8 shows the first three points of a motion diagram. Is the object’s average speed between points 1 and 2 greater than, less than, or equal to its average speed between points 0 and 1? Explain how you can tell. b. Use Tactics Box 1.3 to find the average acceleration vector at point 1. Draw the completed motion diagram, showing the velocity vectors and acceleration vector.

Monarch butterflies belong to one of the most beautiful species of animals. To protect themselves from the cold in Canada and the United States, they fly to Mexico and the countries of Central America in the fall. If they travel an approximate distance of 3,960 km during 60 days,
a) what is the speed of the butterflies in m / s
b) in km / hr
a) A robin flies a distance of 45 963 cm. How far has it flown in kilometres?(b) What is the speed in metres per second of a car that is travelling at 82 km/h? (c) What is the speed in kilometres per hour of a 27.78 m/s baseball pitch?(d) How many seconds are there in a calendar year, given that a calendar year has 365.24 days in it? T/I
