A 1,400-kg car is traveling north at 13 m/s. Calculate the momentum of the car.

O 18,200 kg. m/s north

O 18.500 kg. m/s north

O 19,200 kg•m/s north

0 8.500 kg. m/s north

18200kgm/s north

Explanation:

Given parameters:

Mass of car = 1400kg

Velocity  = 13m/s

Unknown:

Momentum of the car  = ?

Solution:

Momentum is the quantity of motion a body posses.

 It is expressed as ;

 Momentum  = mass x velocity  = 1400 x 13

 Momentum  = 18200kgm/s north

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
