A5.0 kg ball is whirled on a 1.2 m string so that the ball moves in uniform circular motion in a horizontal plane. the centripetal force is 22 n. what is the tangential speed of the ball?2.3 m/s fc=22n m= 5.0kg r= 1.2m vt= √(fc* r /m) √(22n *1.2 / 5.0kg) = 2.3 m/s

The tangential speed of the ball is 2.3 m/s.

Explanation:

Mass of the ball ,M= 5.0 kg

Length of the string to which the ball is tied = r = 1.2 m

Tangential speed of the ball - v

Centripetal force acting = 22 N

The tangential speed of the ball is 2.3 m/s.

the truman doctrine was an american foreign policy whose stated purpose was to counter soviet geopolitical expansion during the cold war. it was announced to congress by president harry s. truman on march 12, 1947, and further developed on july 12, 1948, when he pledged to contain threats to greece and turkey.

condensation. good luck!
