Question
Can somebody answer these two questions please?
Suppose a block with mass m is spun on a string at constant angular velocity in a horizontal circle on a frictionless table. Rank the tension in the string from smallest to largest, given the following conditions: Five spiders are on top of a record that is turning with an angular velocity of 45 revolutions per minute. Rank the following locations according to the acceleration a that a spider would feel at that spot, from smallest to largest. a) Spider A is sitting 5 cm from the center of rotation. b) Spider B is sitting 10 cm from the center of rotation. c) Spider C is 12.5cm from the center of rotation but is walking in a circle concentric with the center of the record, with an angular velocity of negative 45 revolutions per minute so that it appears to be standing still to the outside observer. d) Spider D is also 12.5 cm front the center of rotation1 following spider C, but can only walk as fast as negative 25 resolutions per minute. e) Spider E sits 27.5 cm from the center of rotation.Explanation / Answer
T=mw2R
e<c<a<b<d
a=w2R
c<d<a<b<e
