Certified answers contain reliable, trustworthy information vouched for by a hand-picked team of experts. Brainly has millions of high quality answers, all of them carefully moderated by our most trusted community members, but certified answers are the finest of the finest.

These are estimates of their average speeds
over some duration of time. These are not the fastest speeds.

*Domestic animals *

You could observe their movement in real life. If you observe their speed in meters/sec at home or on road or in some outing, then you can estimate the speed in kmph. You can also estimate their speeds based on the relative speeds like a dog runs faster than a cat.

Cat - 45 kmph Dogs - 50 kmph

Rabbit - 50 kmph Rats - 24 kmph

Lizards - 0.3 kmph Cows - 12 kmph

Bullocks - 12 kmph Goats - 25 kmph

**Wild
animals **

Cheetah - 100 kmph or more

Lion - 50 kmph to 60 kmph - cannot run at high speed for a long duration

Tiger 60 kmph

Elephants - 30 kmph

deer - 50 kmph - can run fast for relatively long duration

Wild horse - 60 km Swan on water - 10 kmph

Wild duck swims - 10 km/hour Rabbit - 20 km to 25 km

Crow - 40 kmph Eagle - 100 kmph or more

Wild dogs - 60 kmph

Crocodile - 10 kmph on land, 20 kmph in water

Fish - 50 to 100 kmph depending on the type of fish

Frog - 18 t o 20 kmph

**Bodies moving
in uniform speed*

1. Earth rotates around itself with a uniform speed (almost)

So all of us are moving with a uniform speed (tangential) in circles, with

respect to a stationary observer outside earth. We have not taken into

account the revolution of earth around Sun here.

Our speed = radius of earth * angular velocity

= 6400 km * 2 π / 24 hours = 1675.5 kmph

2. Trains and air planes move with uniform speed in between halts. Near

stations or airports, they accelerate or decelerate. An express train

covers usually around 60 km in 3/4 hour non-stop between two big stations.

average speed = 60 / (3/4) = 80 kmph

5. Speed of Birds flying in air = distance traveled / time = 15 meters /sec = 54 kmph

7. Hard disk inside the computer. It rotates at uniform speed.

speed = 4,000 rpm - 10,000 rpm

9. Light wave moves at uniform speed of c = 3 * 10^8 m/sec

10. A fan (ceiling) rotates at a uniform speed, same with the blade in a

kitchen - mixie or mixer.

Tip of Fan wing : radius = 0.80 meter,

smallest speed = 5 rotations per sec

Angular speed = 5 * 2 p radians/sec = 10 p rad/sec

Uniform Linear speed of the tip (far end of a wing)

= 0.80 * 10 p m/sec = 25.13m/s = 90.5 kmph

11. Blood inside our body moves (circulates) at uniform speed

Pulse rate = 72 /min

Average distance from heart to a hand/leg = 2.5 m

Speed of blood flow = around 2.5m * 72 / min

= 180 m / min = 180 * 60/1000 = 10.8 kmph

__Bodies moving with non uniform speed :__

1. In a cricket match the cricket ball is bowled and it travels the pitch at

an average speed in air and after bouncing from ground =

The ball takes 0.7 to 1 sec to reach batsman - observation.

speed = distance / time = 20 meters / 0.7 sec = 20/0.7 * 18/5 = 103 kmph for a pacer

and 20 m / 1 sec = 72 kmph for a spinner.

2. moon moves around the Earth with almost uniform speed

4. An object thrown in to air, like stone, moves at non-uniform speed.

4. Earth moves in an elliptical orbit non-uniform speed - its orbital speed

changes depending on its distance from the Sun. During summer Earth is

at 147 million km and (perihelon) during winter, it is at 152 million km.

Linear Speed at perihelon = 2 π R / T = 105,000 kmph

Linear Speed at apihelon = 2 π R / T = 109,000 kmph

5. Lift used to go up or down in a building - it moves at non-uniform speed -

accelerates and decelerates also. Lift reaches 4th floor (10meters) in

10 seconds with uniform acceleration starting from rest.

So acceleration of an elevator is = 20/100 = 0.2 m/s²

Speed = 0.2 * time m/sec
