Question

In each case, a sphere is moving from left to right next to a tape marked in meters. A strobe (flash) photograph is taken every second, and the location of the sphere is recorded. The total time intervals shown are not the same for all spheres. Rank the magnitude of the displacement over the first 2 seconds. Explain your reasoning. In each case, a sphere is moving from left to right next to a tape marked in meters. A strobe (flash) aken every second, and the location of the sphere is recorded. Te total time intervals shown are not pheres.

Explanation / Answer

The phtographs are taken for every 1s, we strat with t=0

at the begining A,B,C are at 0 pos and D is at 1 m

at t= 2s,

D has moved from 1 to 9 , dispalcement = 8m

C has moved from 0 to 6 dispalcement = 6 m

B has moved form 0 to 1m displacement = 1 m

A has moved from 0 to 4 m displacement = 4 m

ranking in oreder from greatest to leaset

D-C-A-B
