How much work must be done on a 6000-kg stone car to increase its speed
from 5 m/s to 10 m/s?

225000J

Step-by-step explanation:

where

W= work done

F=force

S=distance

but F=ma

so we can write the equation

Also,

We put equation (2) and equation (3) into equation (1)

This implies,

From the question

m=6000kg

u=5m/s

v=10m/s

By substitution we obtain

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

maya’s expression will generate the wrong sum because she violated the commutative property.
