Q4. A cyclist starts from the centre O of a circular park of radius 1 km, reaches the edge P of the park, then cycles along the circumference anticlockwise from P to Q, and returns to the centre along QO as shown in Figure. If the round trip takes 10 min, what is the (a) net displacement, (b) average velocity, and (c) average speed of the cyclist ?
Answer : Option D
Explaination / Solution:
(a) displacement is shortest distance b/w initial point and final point, as he returns back to origin after starting from origin, the displacement is zero.
(b) Average velocity =
As displacement is zero, so average velocity is also eqaul to zero.
(c) Radius r = 1 km
distance covered = OP+PQ+QO
=
= km
Time taken = 10 minutes = hour
Average speed
21.4 km/h
