Explanation:

Acceleration ,a = -10m/s² (opposite direction of motion)

Final velocity ,v = 0m/s

Time taken ,t = 5s

To Find:-

Distance covered by the car before coming to rest ,s

Solution:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀According to the Question

Firstly we calculate the initial velocity of the car . Using 1st equation of motion

v = u + at

where,

v is the final velocity

a is the acceleration

u is the initial velocity

t is the time taken

Substitute the value we get

:\implies:⟹ 0 = u + (-10) × 5

:\implies:⟹ -u = -50m/s

:\implies:⟹ u = 50m/s

So the initial velocity of the car is 50m/s

Now, calculating the final velocity of the car by using 3rd equation of motion.

v² = u² + 2as

Explanation:

Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.[1][2]

The source of Earth's solar power: the Sun

It is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air.

The large magnitude of solar energy available makes it a highly appealing source of electricity. The United Nations Development Programme in its 2000 World Energy Assessment found that the annual potential of solar energy was 1,575–49,837 exajoules (EJ). This is several times larger than the total world energy consumption, which was 559.8 EJ in 2012.[3][4][needs update]

In 2011, the International Energy Agency said that "the development of affordable, inexhaustible and clean solar energy technologies will have huge longer-term benefits. It will increase countries' energy security through reliance on an indigenous, inexhaustible, and mostly import-independent resource, enhance sustainability, reduce pollution, lower the costs of mitigating global warming, and keep fossil fuel prices lower than otherwise. These advantages are global. Hence the additional costs of the incentives for early deployment should be considered learning investments; they must be wisely spent and need to be widely shared".[1]
