Give one word of the following.
A time interval that equals 3600s
Unit of time is the second.
We know
3600sec=60×60s=60minutes[1min=60s]=1hour[1hour=60min]
Hence, A time interval that equals 3600s is 1hour.
Figure 3.24 gives the x-t plot of a particle in one-dimensional motion. Three different equal intervals of time are shown. In which interval is the average speed greatest, and in which is it the least? Give the sign of average velocity for each interval.
