A. The fastest bird is the spin-tailed swift and the slowest bird is the mallard.
B. the dive speed of the peregrine falcon is faster than any other birds given in the question.
What is speed?
The speed at which an object's location changes in any direction. The distance traveled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.
Here, we have
A. the speed of a spin-tailed swift is 2843.2m/min.
We have to convert the speed to m/sec.
From above we know that,
1 min = 60 sec
2843.2 m/min = 2843.2m/1minm
2843.2/60 = 47.386m/sec
2843.2 m/min = 47.386m/sec
The speed of a spur-winged goose is 129.1ft/sec.
We have to convert the speed to m/sec.
From above we know that,
1ft = 0.3048m
129.1ft/sec = 129.1/1sec
129.1ft/sec = 39.349m/sec
Hence, from the above, we can say that the fastest bird is the spin-tailed swift and the slowest bird is the mallard.
B. From part (a) we get,
The speed of the different birds in m/sec is given below:
Spine tailed swift
2843.2m/min = 47.386m/sec
Spur-winged goose
129.1ft/sec = 39.349m/sec
Eider duck
31.3m/sec
Mallard
65mi/h = 29.051m/sec
The dive speed of the peregrine falcon is
322km/h = 322km/1h
= 322(1000)m/1(3600)sec
= 89.444m/sec
Hence, the dive speed of the peregrine falcon is faster than any other bird given in the question.
