Please help me solve these questions using velocity and acceleration formulas. Please try to give the answer written on a notebook showing the work. It is easier for me to understand that way. You can use a format I'll provide below the questions to answer. Thank you, I appreciate your help!

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 3 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? 2. 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) QL (m) Position-Time 20 15 10
