Sonic boom from a plane is an example of a shockwave. Give another example where a shockwave is produced

A car is moving at a speed of 60 m/s, when the driver applies the brakes, which causes a deceleration of 2 m/s2. How many seconds will it take for the car to stop and how far will it travel till it stops

the speed of a train is decreased in a uniform rate from 96 km/h to 48km/h through a distance of 800m. calculate the distance covered by the train from the moment of using the brakes till it stops if it was moving with the same acceleration
