The specific heat of soil is 0.20 kcal/kg*c and the specific heat of water is 1.00 kcal/kg*c. this means that if 1 kg of soil and 1 kg of water each receive 1 kcal of energy, ideally.

The soil will be warmer than the water.

Explanation:

The heat (thermal energy) absorbed can be found using the following equation:

Where:

is the heat  

is the mass of the element

is the specific heat capacity of the material.

is the variation in temperature

In the case of soil we have:

(1)

Where:

In the case of water we have:

(2)

Where:

Isolating from both equations:

(3)

(4)

(5)

(6)

Comparing (4) and (6) we can find the soil will be warmer than the water.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

the answer is b, have negligible mass
