Answer:
<em>x = 55 ; y = 60</em>
Step-by-step explanation:
Ok so differnce of 2 perfect ssquares are
x^2-y^2=(x-y)(x+y)
we are given
one factor is 5x-8
remember that all you do is square both terms individually to get them
(5x)^2=25x^2
8^2=64
they are difference so
25x^2-64 is answer
The kinetic energy of the roller coaster is 2000Joules
Given the formula for expressing the velocity of the roller coaster is given as:

Given the following parameter:
v = 10m/s
Substitute the given parameter into the formula to have:

Square both sides of the equation:

Hence the kinetic energy of the roller coaster is 2000Joules
