A car finishes 4 laps, each of 4 miles. Identify the correct representation of the distance covered in 4 laps using the number line.
When a body repeats its motion in regular interval of time then it's said to execute periodic motion. Let's say a car is going on a race track (as shown in figure)
The car covers 5 laps.
For each lap it took 10 mins
In which of the below mentioned cases will its motion be considered periodic.
Case I: The car was travelling with constant speed.
Case II: The car had a constant acceleration from rest (0 m/s) and then a constant deceleration to rest (0 m/s) in each lap for all 5 laps.
Case III: The car had a non-uniform acceleration throughout the journey.
Case IV: lap 1 with constant speed, lap 2 with constant acceleration, lap 3, 4, 5 with variable acceleration.
