Given:
- \mbox{In one time interval, a ball rolls down the incline 0.8 meters.}
Question:
- \mbox{What interval does the ball travel in the second and third time intervals?}
Rationale & Calculate:
- \Delta{x} \varpropto t^2
- \Delta{x-1} = 1 * K
- \Delta{x-2} = 4 * K
- \Delta{x-3} = 9 * K
- K = 0.8 \; \mbox{since at t-1, x-1 is 0.8}
- \Delta{x-2} = 3.2
- \Delta{x-3} = 7.2
- Interval_{2-1} = 3.2 - 0.8 = 2.4
- Interval_{3-2} = 7.2 - 3.2 = 4.0
