Acertain car going from atlanta to philadelphia averages 24.0 m/s over the course of the trip. determine how long it takes the car to reach philadelphia if 1,250 km away from atlanta by road. report your answer in hours. (be careful of units! )

14.5 hours

Explanation:

The relationship between speed, time and distance for a uniform motion is

where

v is the speed

d is the distance

t is the time taken

Here we know:

v = 24.0 m/s is the average speed

is the distance

Solving the equation, we find the time taken:

And since

1 hour = 3600 s

The time in hours is

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
