A car of mass 1500 kg is moving with a velocity of 72 km/h. When the driver applied brakes, the velocity of the car reached 10 km/h by travelling the distance of 50 m. Calculate the amount of force applied in the car during that time.

Answers

Explanation:

friend I have solved it as we know that force = mass *acceleration and by the equations of motion

To solve this, we must be knowing each and every concept related to force and its calculation. Therefore, the amount of force applied in the car during the time is 6000N.

What is fundamental force?

Nature is governed by four fundamental or universal forces. All stuff in the universe would disintegrate in the absence of these forces. Any pull or push that causes an item to change its physical condition is referred to as force (in terms of motion or deformity).

Mathematically,

V²-u²=2aS

V=72 km/h=72000/3600=20m/s

u=0m/s

s= 50 m

substituting all the given values in the above equation, we get

20²-0²=2×a×50

a=4m/s²

Force = mass ×acceleration

substituting all the given values in the above equation, we get

1500 kg=mass

Force = 1500 ×4

         =6000N

Therefore, the amount of force applied in the car during the time is 6000N.

Force = mass x acceleration

F= ma (formula)

15N = o.5kg x a

Divide both sides by o.5

a = 30 (greater acceleration)

15N = 4.5kg x a

Divide both sides by 4.5

How can this erosion be prevented?

Answers

Answer:

Soil erosion by water occurs when bare-sloped soil surface is exposed to rainfall, and the rainfall intensity exceeds the rate of soil intake, or infiltration rate, leading to soil-surface runoff.

Explanation:

Surface cover and runoff. Surface cover is a major factor to control erosion because it reduces the impact of raindrops falling on bare soils and wind removing soil particles. It also reduces the speed of water flowing over the land. Erosion risk is significantly reduced when there is more than 30% soil cover.

The time  taken for anna to move the box the distance of 9.72 meters is 25.9 seconds. The correct option is c.

What is force?

The force is the action of push or pull to move or stop an object.

Anna pushes a box with a force of 8.00 newtons. she generates a power of 3.00 watts.

Force is related to power by the relation

Force = Power / Velocity

Put the values, we get

8 = 3/V

V = 0.375 m/s

Velocity is defined as the ratio of distance and the time taken.

The box is moved by the distance of 9.72 meters. So, time taken is

V = d/t
