A marble launcher is set up to launch marbles in the horizontal direction. It has a spring constant of 190 N/m and a marble of mass 0.0059 kg is loaded and compresses the spring 0.071 m. What is the speed of the marble when it exits the launcher?

fgravity=10x10=100n case 1

fgravity=30x20=600n case 2

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray

magnets not strong enough

explanation:

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
