A centrifuge consists of a container held at a distance of 0.20 m from its axis. When turned on the centrifuge spins the container and its contents round at 9000 revolutions per minute. a) Find its angular velocity, b) A small mass of 10 g is placed in the drum. Work out what force will need to be provided for it to go round at that rate in a circle of radius 0.20 m.

Explanation:

a) ω = 9000 rev/min (2π rad/rev) / 60 s/min = 942.47779... = 940 rad/s

b) F = mω²R = 0.010(942.4777²)0.20 = 1,776.52879... = 1800 N

he kicked it 10 feet straight up into the air? i think this works.

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.
