1) A vehicle approaches a school zone it decelerates from 50km/hr to 30km/h at a rate of 1.1m/s^2. How long did it take to change speeds?2) An object falls 210m in 6.3s. Measured in m/s, what is the object's initial velocity? 3)

The graph shows the velocity of an automobile as it accelerates uniformly to its cruising speed. What is the displacement of the car in the first 12 s of acceleration? Use the following information to answer the next question. Velocity-Time 40 30 Velocity (m/s) 20 10 4.0 8.0 120 160 Time (9) Select one: O a. + 90m b. + 100 m O c. + 180 m O d. + 360 m Check
