The mechanical energy of the car is
Explanation:
The mechanical energy of an object is equal to the sum of its gravitational potential energy (GPE) and its kinetic energy (KE):
E = GPE + KE
The GPE of the car is given by:
where
m = 1000 kg is the mass of the car
is the acceleration of gravity
h = 30 m is the height of the car above the ground
Substituting,
The kinetic energy of the car is given by:
where
m = 1000 kg
v = 50 m/s is the speed of the car
Substituting,
Therefore, the mechanical energy is

Answer:
linear perspective
Explanation:
Railroad tracks appear to converge due to our field of view. When an object is far away it seems smaller that means there is angle that subtends from our line of sight this results in the illusion of railroad tracks converging.
Railroad tracks converging activates the linear perspective of our vision. Linear perspective is a technique used to convey a sense of depth in two dimensional representation of an object. The lines at an angle give us a sense of depth otherwise straight lines will not be able to convey depth.
