Question

A particle is moving in a circle of diameter 14m. What is its distance and displacement as per the table given below
1 ROUND
1.5 ROUND
2 ROUND
2.5 ROUND

Answer 1

Answer:

$1 \: round \\ distance = \pi \: d \\ = \pi \: 14 \\ = \frac{22}{7} \times 14 \\ = 22 \times 2 \\ = 44m \\ displacement = 0 \\ \: as \: starting \: and \: ending \: point \: are \: same \\ 1.5 \: round \\ distance = \pi \: d \\ = \pi \: 1.5m \\ displacement = diameter = 14m \\ 2 \: round \\ distance = \pi \: d \\ = \pi(14 \times 2) \\ = \frac{22}{7} \times 28 \\ = 22 \times 4 \\ = 88m \\ displacement = 0 \\ as \: starting \: and \: ending \: point \: are \: same \\ 2.5 \: round \\ distance = \pi \: d \\ = \pi \: 2.5m \\ displacement = diameter = 14m$
