Which of the following graphs applies to each situation? Each graph shows the behaviour of two objects; east is in the direction of positive d. (E.g., if graph A applies to situation 1, and C to the rest, enter ACCCCC) 1) A jogger overtaking a walker. 2) A race car speeding up to match the speed of a second race car. 3) A car moving at a steady speed is overtaken by a police car starting from rest. 4) An initially moving truck speeding up eastward and a west- ward moving truck slowing down. 5) A ball thrown upward and a ball thrown downward at the same time with the same initial speed. 6) A car, initially at rest, accelerating and a car moving ini- tially at constant speed applying the brakes until it stops. A) B) t D) E) F) G) H) I) J)

1) The motions of a car and a motorbike along a straight road are described by the velocity vs time graph provided below. The two vehicles are initially alongside each other at time t=0 s. The motorbike’s speed is 18.1 m/s and the time T is 59.9  s.  a) what distance has the motorbike travelled between 0 and T (in km)? b) What distance has the car traveled between 0 and T (in km)? 2) Which of these statements is true? a. At T, the car and motorbike are at the same location. b. the acceleration of the car is constant between 0 and T  c. the acceleration of the motorbike is 0 d. the acceleration of the car is 0  3) a)What is the car's average speed for the first T seconds? (in m/s) b) What is the motorbike's average speed for the first T seconds (in m/s)

A bus makes a trip according to the position-time graph shown in the drawing. What is the average velocity (magnitude and direction) of the bus during each of the segments A, B, and C? Express your answers in km/h. The scale for the time axis is 2 h per increment, and scale for the velocity axis is 210 km per increment.

Consider a coordinate system with Stephen's home as the origin for questions 7-9. Watch out for positive and negative signs! 7. Stephen rode his skateboard 5.0 km from his home to school. What is his displacement?

Below is another motion diagram for an object that moves along a curved path. The dots represent the position of the object at five subsequent instants, t1. t2, t3, t4, and t5. The vectors v21, v32, v43, and v54 represent the average velocity of the object during the four corresponding time intervals. Draw the acceleration vectors a31 and a53 representing the changes in velocity of the object during the time intervals At31 = t3 - ti and At53 = t5 –t3, respectively. Draw the vectors starting at the appropriate black dots. The location, orientation, and length of the vectors will be graded. Vectors: āsa Acceleration between times 3 and 5 ās1 acceleration between times 1 and 3 -vas Vector opposite to v43 -v21 Vector opposite to v21
