a 2 100 kg car drives east towards a 55 kg shopping cart that has the velocity of .50 m/s west. The two objects collide, giving the car a final velocity of 6.31m/s east and the shopping cart a velocity of 13.5 m/s east. What was the initial velocity of the car?

"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.

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
