Question

A truck is of mass 50,000kg. Its tyres exert pressure of 2,500,000Pa. The surface area of tyres in contact with ground is

Answer 1

mass = 50000 kg

pressure = 2500000 Pa

we know ,

pressure = Force / area

area = force / pressure

= mg/pressure

= (50000 x 10) / 2500000

= 500000/2500000

= 5/25

= 1/5

Answer 2

Hey there!

Given,

Mass (m) = 50 000 kg

Pressure (P) = 2,500,000 pa

Force (F) = ?

Area (A) = ?

We know,

Force= Mass  * acceleration

         = 50 000 * 10

         = 5 00 000 N

And,

Pressure = Thrust / Area

Area = thrust / pressure

Area = 5,00,000 / 2500000

Area = 5/25

Area = 1/5 sq. unit
