Answer:
The answer to your question is: -6m/s²
Explanation:
Data
vo = 30 m/s
vf = 12 m/s
t = 3 s
a = ?
Formula
vf = vo + at
a = (vt - vo) / t
Process
a = (12 - 30) / 3 substitution
a = -18 / 3 simplify
a = -6 m/s² result, is negative because the car
is slowing down.
Answer:
The kinetic energy of the phone would increase. The gravitational potential energy of the phone would decrease.
Explanation:
The kinetic energy 
of an object is proportional to the square of the speed of that object. If air resistance is negligible, the phone would accelerate under gravitational pull and speed up. Hence, the kinetic energy of the phone would increase.
The gravitational field near the surface of the earth is approximately constant. Hence, the gravitational potential energy 
of the phone would be proportional to its height. As the phone approaches the ground, the height of the phone becomes lower and the gravitational potential energy of the phone would decrease.
Answer:
opposite the sun. between the Earth and the sun. rising perpendicular to the sun.
Explanation:
Answer:
Potential energy is energy that is stored – or conserved - in an object or substance. This stored energy is based on the position, arrangement or state of the object or substance. You can think of it as energy that has the 'potential' to do work.
