This is confusing me .....

Under which of the following conditions is the magnitude of the average velocity is SMALLER than the average speed over some time interval?!!

a) A particle moves in the +x direction without reversing ..

b)A particle moves in the -x direction without reversing ..

c) A particle moves in the +x direction and then reverses the direction of it motion.

d) there are no conditions for which this is true.

i think its c ...am i right ?

anonymous · Answer

yes, because reversing will introduce negative velocities that will bring the average down. speed has no direction so no negatives and so the average will be bigger than that of the velocity.
