Question

AYUDAAAAAAA Un ciclista de montaña se mueve cuesta abajo por la pendiente, si acelera a 3 m/s2 y se demora en bajar 15 minutos (900 segundos) ¿Qué distancia recorre? AYUDENME PORFAVOOOR

Answer 1

The question is: HELPAAAAAAA A mountain biker moves downhill if he accelerates at 3 m / s2 and takes 15 minutes (900 seconds) down, how far does he travel? HELP ME PLEASE

Answer: The distance travelled by the mountain biker is 2430 km.

Step-by-step explanation:

Given: Acceleration =
`3 m/s^(2)`

Time = 15 minutes (900 sec)

Displacement = ?

Formula used to calculate the final velocity is as follows.

`v = u + at`

where,

v = final velocity

u = initial velocity = 0 m/s (here)

t = time

a = acceleration

Substitute the values into above formula as follows.

`v = u + a * t\\v = 0 + 3 m/s^(2) * 900 s\\= 2700 m/s`

The relation between velocity (speed) and distance is as follows.

`Speed = (Distance)/(time)\\2700 m/s = (Distance)/(900 s)\\Distance = 2430000 m (1 m = 0.001)\\= 2430 km`

Thus, we can conclude that distance travelled by the mountain biker is 2430 km.
