You hold glider a of mass 0.125 kg and glider b of mass 0.375 kg at rest on an air track with a compressed spring of negligible mass between them. when you release the gliders, the spring pushes them apart. once the gliders are no longer in contact with the spring, glider a is moving to the right at 0.600 m/s. what is the velocity (magnitude and direction) of glider b at this time?
glider a moving to the right at 0.600 m/s then collides head-on with a third glider c of mass 0.750 kg that is moving to the left at 0.400 m/s. after this collision, glider c is moving to the left at 0.150 m/s. what is the velocity (magnitude and direction) of glider a after this collision?

a) final velocity of glider B = 0.20m/s ( in the left direction)

b) final velocity of glider A = 0.9m/s ( in the left direction)

"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.

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
