Question

A peregrine falcon is the fastest animal in the world. When it dives, it can accelerate to

Answer 1

The speed of the falcon is 144 km/h

Explanation:

The speed of a body is a scalar quantity telling how fast the object is moving, without giving any information about its direction.

It can be calculated as:

$speed = \frac{d}{t}$

where

d is the distance covered

t is the time taken

In this problem, the falcon has a speed of

$speed = 40 m/s$

We want to convert it into km/h. Let's keep in mind that:

1 km = 1000 m

1 h = 3600 s

Therefore, we convert as follows:

$speed = 40 \frac{m}{s} \cdot \frac{3600 s/h}{1000 m/k}=144 km/h$
