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.

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 \times t\\v = 0 + 3 m/s^{2} \times 900 s\\= 2700 m/s

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

Speed = \frac{Distance}{time}\\2700 m/s = \frac{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.

If you were trying to kill a fish with a spear, would you aim where you see the fish
34kurt
No, you would aim slightly above, because when you throw the spear and it travels through the air it will fall slightly downwards by the time it reaches the fish.

Describe the atomic structure of hydrogen atom.
-Dominant- [34]

Answer and Explanation:

The hydrogen atom is an atom of hydrogen element.Hydrogen atoms contain one proton which has positive charge and one electron which has negative charge , so due to positive and negative charge present in the hydrogen atom its becomes neutral atom.In whole universe the hydrogen atom is found in most abundant. Electron and nucleus of the hydrogen atom is bound together with the help of coulomb force.

The box is pushed to the left with 30 N of force, but does not move. What is the Friction Force?​
Andrews [41]

However here coefficient of friction is not given so unable to calculate.

You can calculate it by below formula.

The formula given by

\\ \sf\longmapsto F_f=\mu N

Or

\\ \sf\longmapsto F_f=\mu mg

u is coefficient of friction

N is normal reaction.

Here..

box doesn't move means the force if limiting friction is greater than applied force.
