A book has a mass of 50 kilograms and an acceleration of 5 m/s/s. What is the force on the book?

The force on the book is 250N.

Step-by-step explanation:

Newton's second law states that the equation for the force is:

In which m is the mass, in kilograms, and a is the acceleration, in m/s². F is the force measured in N.

In this question:

So

The force on the book is 250N.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
