Introduction

During an Airplane Crash in Jakarta, controversies regarding about what actually happened before and after has been emerging all the time. But what really happens after the airplane crash? Who were involved?

1. Sketch a speed-time graph of the airplane from the first time it moves until it contacts the skyscraper (spring block).

1. The plane travels a distance of 2.25m before coming into contact with the spring block. It took the plane 0.78s to hit the block. What is the average velocity of the plane before crashing into the block?

1. After the airplane crash, it turned out that the person inside the airplane who is responsible for the event was picked up by his teammate in a black BMW Z4! The police tried tracking the car, but couldn’t find where they are going and how long it took them to go to their destination because they don’t have any stopwatch or anything that measures time; However, they do have their final velocity, which is 2.83 m/s, and acceleration, which is - 0.65 m/s/s Find the time the car traveled to its destination (by the time it hits the block in front of it) without a stopwatch. (Note: There is a ruler on the road)

1. It turned out that you are too slow to find the time it took for the black car to reach its destination. The good news is that the police have found their stopwatch! They actually headed towards Fat Car Co. and succeed to escape with a stolen white Range Rover. They have succeed to turn off the road’s navigation system (no distance!) and reached their destination. Use the graph in Algodoo to find out the displacement the car traveled from Fat Car Co. to the shop.
