Acar traveling at 30 m/s runs out of gas while traveling up a 10 slope. how far up the hill what coast before starting to roll back down?

264.7 m

Explanation:

The net force felt by the car travelling along the slope is equal to the component of the weight parallel to the slope, so:

where

m is the mass of the car

g = 9.8 m/s^2 is the acceleration of gravity

and the negative sign is due to the fact the force is opposite direction to the motion of the car

The acceleration of the car is therefore:

Now we can find how far the car went up the hill by using the equation:

where

v = 0 is the final velocity of the car

u = 30 m/s is the initial velocity

g = -1.7 m/s^2 is the acceleration

d is the distance covered

Solving for d,

snell's law

refractve index = sin incidence / sin refraction

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
