The scalar reading during the process is 170. 5 Newton
<h3>
How to determine the scalar reading</h3>
force = mass × acceleration
Given the mass = 55kg
In finding the acceleration, use the first equation of motion
v = u + at
u = 0
t = 2s
v = 6.5 m/s
Substitute the values
6.5 = 0 + 2a, make 'a' the subject
a = 6. 5÷ 2 = 3. 1 m/s²
Substitute the value of 'm' and 'a' in the original equation
F = 55× 3.1 = 170. 5 Newton
Hence, the scalar reading during the process is 170. 5 Newton

- It helps in regulating extremes in the environment.
- It can be used as a car radiators.
<u>Explanation:</u>
- The amount of heat needed to raise a certain amount of temperature to the water is known as the specific heat of the water. For one gram of water to increase 1 degree celsius, water needs to absorb 4.184 J of heat.
Some of the uses of high specific heat of water are as follows,
- The temperature of the water will remain the same from day to night in ponds or sea. During day time, the hot air from the sea or pond rises while the cool air from the sea moves to take its place. During the night, the hot air from the land moves to take its place, giving rise to a land breeze and thus maintaining the environment.
- Another example, When water is circulated throughout an engine, heat will get absorbed. This water is pumped to a radiator and then disposed to the surrounding air.
Eating. Your muscles in your arms and mouth use energy to feed itself. Then your body digest the food which also takes energy.
Sleep. When your tired, you don’t have much energy. It is said that you use more energy while your sleeping. But how do you become energized if you were using even more energy than before?
Is the initial velocity or time given?
