Questions 1. An object is pushed from rest across a sheet of ice, accelerating at 5.0 m/s2 over a distance of 80.0 cm. The object then slides with a constant speed for 4.0 s until it reaches a rough section which causes it to stop in 2.5 s. (6 marks) a. What is the speed of the object when it reaches the rough section? b. At what rate does the object slow down once it reaches the rough section? c. What total distance does the object slide throughout its entire trip? . A dog's position is recorded in the graph below. Determine the velocity of the dog in all three segments. Sketch the corresponding velocity-time graph. (9 marks) Elm) PositionTime 17 [m/s) _ . 15 VeIOCIty-Tlme 3. A sports car's velocity is shown in the graph below. (8 marks) a. How fast is it traveling at the 5 3 mark? 10 b. What is the acceleration at the 5 3 mark? c. Estimate the acceleration at the \"5) 15 3 mark. Show your work. 5 10 15 2 d. During which intervals of time, did the car have a negative acceleration? 4. Using the acceleration-time graph below, sketch the corresponding velocity- time graph. Show your work.
