Y=-2/3x + 2
y=3x-2
one because the slopes are different
Answer:
The kinetic energy is 20,000\ J
Step-by-step explanation:
The kinetic energy of a body is defined as:

Where <em>m</em> is the mass of the roller coaster car
<em>s</em> is the speed and <em>k</em> is the kinetic energy
We know that 

Then the kinetic energy of the roller coaster car is:

Answer:
Step-by-step explanation: the pattern is going positive to negative and going further away from zero so the next term would be -3
