H= 3 V/ Ab =3 x 168/36 = 14 cm
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:
5y+3x=123
Step-by-step explanation:
(x1,y1)=(1,24), m=-0.6
y-y1=m(x-x1)
y-24=-0.6(x-1)
y-24=-6/10(x-1)
10(y-24)=-6(x-1)
10y-240=-6x+6
10y+6x=6+240
10y+6x=246
divide by through by 2
5y+3x=123
