Question

A motorcycle weighs 1200 N. If the pressure exerted by one of its tyres is 120 Pa, then find the
area of the tyre in contact with the road.​

Answer 1

Explanation:

A motorcycle has two wheels.

If one wheel exerts pressure of 120Pa, then both wheels would exert 240Pa.

Pressure exerted = 240Pa

Force (weight) = 1200N

We know,

Pressure = Force (Thrust) / Area

240 = 1200 / Area

Area = 1200/240

Area = 5m²

Now, this area is of both tyres

So one tyre would have area of 2.5m².
