Question

2 out of 10 attempts Starting with the left-most column, populate the boxes from left to right without skipping empty boxes. Ties should be grouped in the same box 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 25 cm 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 25 cm from the center of rotation, following spider C, but can only walk as fast as negative 25 revolutions per minute. e) Spider E sits 30 cm from the center of rotation.

Explanation / Answer

accelaration is a = r*alpha

alpha is the angular accelaration

and r is the disance from axis of rotation to the particle

alpha is constant for each spider

the smaaler is the r then smaller is the accelaration a

So among all the spiders A was sitingsmallest distance (5 cm) from the center of rotation

So the Spider which has smallest a is A

next smallest is B

Next smallest is C

C andD are at the same distances ,but by using angular momentum ,C has smallest a than D

next smallest is D

last one ,largest a is possessed by spider E
