Un tren viaja inicialmente a 16m/s se acelera constantemente a razón de 2m/s2 en la misma dirección. ¿Cuán lejos viajará en 20s?

d = 720 s

Explanation:

The question says, "A train initially traveling at 16m / s accelerates constantly at a rate of 2m / s2 in the same direction. How far will it travel in 20s?"

Initial speed, u = 16 m/s

Acceleration, a = 2m/s²

We need to find the distance covered by it in 20 seconds. Let the distance is d. Using the second equation of motion,

So, it will cover 720 m in 20 seconds.

we need answer choices

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
