A0.180-kilogram car traveling at 0.80 m/s to the right collides with a 0.100-kilogram cart intially at rest. the carts lock together upon collison. calculate the final velocity of the carts

0.51 m/s to the right.

The two carts lock together. As a result, the collision is inelastic. Kinetic energy will not conserve. Still, momentum conserves.

What's the momentum p of the two carts?

Before the collisions:

Momentum conserves. As a result,

Velocity is the same for the two carts after the collision. Let denote that velocity.

.

Direction of the movement will stay the same. Both cars are now moving to the right.

the answer is c i did the same question so i know that's right!

"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.
