A cart with a mass of 120 kilograms and a velocity of 3.5 meters per second collides with a stationary dumpster. Both the cart and the dumpster are free to roll in any direction. The cart and the dumpster stick together after the collision. What other information is needed to determine the final momentum of the dumpster? A. the mass of the dumpster B. the initial velocity of the dumpster C. the kinetic energy of the cart before the collision

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

conduct current i mean it makes sense

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
