A una velocidad de 20 m/s una liebre se desplaza y, comienza a detenerse a razón de 3 m/s cada segundo. ¿Cuánto avanzó antes de detenerse? (Redondea a enteros y no olvides las unidades.)

d = 66.67 m

Explanation:

At a speed of 20 m / s a hare moves and begins to stop at a rate of 3 m / s every second. How far did it go before stopping?

Given that,

Initial speed of hare, u = 20 m/s

Final speed of hare, v = 0 (stops)

Acceleration, a = 3 m/s²

We need to find how far it go before stopping.

Let it will cover d distance before stopping.

Using third equation of motion to find it.

So, it will cover 66.67 m before stopping.

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
