Question

a car starts decelerating on applying brakes and stops after travelling 10 m. if braking force 3 multiply 10⁵N, taluk plate amount of work done by the brakes​

Answer 1

Answer:

3×10⁶ joules is the required answer

Explanation:

Given:-

Displacement of the car ,s = 10m

Force applied on the car ,F = 3×10⁵ N

To Find:-

Work Done ,W

Solution:-

According to the Question

It is given that car starts decelerating on applying brakes and stops after traveling 10m if breaking force is 3×10⁵N.

We have to calculate the work done by the brake .

As we know that work done is calculated by the product of force & displacement.

W = Fs

where,

W denote work done

F denote Force

s denote Force

Substitute the value we get

→ W = 10×3×10⁵

→ W = 3×10⁶ J

Hence, the work done by the car is 3×10⁶ joules.
