We look at the criteria to select a car.

If we are not too rich, we have to bother about fuel efficiency. The mileage in terms

of km per liter or miles per gallon etc.

engine power - whether it is good enough over a slope (steep) that I may encounter

frequently with my family members.

internal space / total external size : or internal space / total price:

We find these numbers. after all , we make use of the internal space on seats.

we have to know its proportion in the total volume of the car.

the axle turning capability, wheel turning ability :

see the minimum radius and span required to turn a car in a U turn.

we have to bother about its pollution, emission level.

height / width ratio, which is important for the balance of the car.

==================================

If we are looking at the economic point of view

monthly benefit/savings of using the car,converted into currency - Loan EMI

**Answer:**

Chemical energy

**Explanation:**

Chemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy. Chemical energy is converted to thermal energy when people burn wood in a fireplace or burn gasoline in a car's engine.

What is the question you need help with

**89.67J**

**Explanation:**

Given parameters:

Mass of rock = 6.1kg

Height of fall = 1.5m

Unknown:

Potential energy = ?

Solution:

The potential energy is the energy at rest or due to the position of a body.

Potential energy is mathematically expressed as;

Potential energy = mgh

m is the mass of the rock

g is the acceleration due to gravity of the rock

h is the height of the rock

Potential energy = 6.1 x 9.8 x 1.5 = **89.67J**
