Two carts are stationary with a compressed spring between them and held together by a thread. When the thread is cut, the two carts move apart. After the spring is released, one cart m=3.00 kg has a velocity of 0.82 m/s east. What is the magnitude of the velocity of the second cart (m=1.70 kg)after the spring is released?

i wanna say it’s between b and d, leaning more towards b.

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.

it would be c. predictability
