Question

Refer to Figure 2.9(b). An insect flying
at a constant speed of 50 cm/s flies from
A to B, B to C and C to A. (a) What is its
displacement? (b) What is the total distance
it covers? (c) How much time does it take to
return to A?​

Answer 1

Answer:

displacement=5m , total distance it cover =7m

Explanation:

as time = distance/speed

=7/0.5

=14 sec

Answer 2

Answer:

the displacement is the distance between the initial point and the final point,

since here it returns to the initial point,

displacement=0

total distance travelled, according to the figure=12m

if it travels at a rate of 50cm/s

that is it covers 50cm in 1s or

0.5m in 1s,

then to cover 12m it takes: 12/0.5=24s
