Chemical energy in the grass is transformed into thermal energy in the rabbit.

B.
Electrical energy in the grass is transformed into thermal energy in the rabbit.

C.
Mechanical energy in the rabbit is transformed into electrical energy in the grass.

D.
Thermal energy in the rabbit is transformed into mechanical energy in the grass.

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
