Question

calculate the work required to be done to stop a car of 1000 kg moving at a velocity of 50 km/hour​

Answer 1

Answer:

The work required to stop the car is 50,000 joule .

Step-by-step explanation:

Given as :

The mass of the car = m = 1000 kg

The velocity of the car = v = 50 km/hours

Let The work required to stop the car = w joule

According to question

work done = force × displacement

∵ Force = mass × acceleration

So, Work done = mass × velocity

Or, w = m × v

or, w = 1000 kg × 50 km/h

Or, w = 50000 joule

So, The work required to stop the car = w = 50,000 joule

Hence, The work required to stop the car is 50,000 joule . Answer
