A car starts from the place with an acceleration 2 m/s and is accelerating during 10 seconds, then travels with the same speed for 30 seconds, then decelerates at the rate 3 m/s until stopping. Show the graph v(t). Calculate the total time of the trip and the distance covered in each interval and the total distance covered by two methods: 1) Calculation of the area under the line v(t); 2) Using the formula for the distance in the motion with constant acceleration. t V 0 VI 2 12 3 13 A car starts from the place with an acceleration 2 m/s and is accelerating during 10 seconds, then travels with the same speed for 30 seconds, then decelerates at the rate 3 m/s until stopping.
