Answer:
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.

Answer:
(-5, -3)
Step-by-step explanation:
Scale factor 1/2 means divide points by 2
Answer:
A.) k=0.5
Step-by-step explanation:
If we use the formula given: y=kx, we can plug in values.
0.5=k(1)
0.5=(0.5)(1)
0.5=0.5
We know that to get from 1 to 0.5, we need to divide by two, or multiple by 1/2. 1/2 in decimal form is 0.5
