What is the speed of the tip of the minute hand whose length is 10cm ?
Asked by veenagairola1 | 26 May, 2014, 08:15: PM
answered-by-expert Expert Answer
Given length of the minute hand (r) = 10 cm = 0.1 m
Distance travelled by minute hand in one complete revolution(d) is Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '. = 2 × 3.14 × 0.1
d = 0.628 m
Time taken in one complete revolution by the minute hand (t) = 1 minute = 60 sec.
Speed of the tip of the minute hand = d / t
= 0.628 m / 60 s
= 0.0105 m/s
Speed of the tip of the minute hand=0.0105 m/s

Two hockey players of opposite teams, while trying to hit a hockey ball on the ground collide and immediately become entangled. One has a mass of 60 kg and was moving with a velocity 5.0 m s–1 while the other has a mass of 55 kg and was moving faster with a velocity 6.0 m s–1 towards the first player. In which direction and with what velocity will they move after they become entangled? Assume that the frictional force acting between the feet of the two players and ground is negligible.
