The kinetic energy of the soccer is 2.25 J.
The kinetic energy of the soccer is the energy possessed by the soccer due to its motion and the can be determined using the following formula;
K.E = ¹/₂mv²
where;
Substitute the given parameters and solve for the kinetic energy of the soccer.
K.E = ¹/₂ x 0.5 x (3)²
K.E = 2.25 J
Thus, the kinetic energy of the soccer is 2.25 J.

Answer:
Step-by-step explanation:
On day one = few pages (x)
On day two = twice of pages read on day one (2x)
On day three= 6 less than the page read the first day (x-6)
Total pages read = x+2x+(x-6)=458
4x-6=458
4x=458+6=464
x= 464÷4
x=116
Pages read on day three was 110
