HELLO DEAR,

Question :Suppose a car is modelled as a cylinder moving with a speed v. If A is the area of cross - section of the car , l is length of car and p is the density of car. Find the mass of the car?

Solution: cross section area of car = A

and length of car = l

So, volume of car = (A ×l)

And density p = mass/volume

Therefore mass = p × volume

m= p × A× l

m= pAl. Answer.

I HOPE IT HELP YOU DEAR,

THANKS.
