Question

A motorcycle weighs 1200N. 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

Answer:

10 m²

Explanation:

Given :

• Force exerted by the motorcycle = F = 1200 Newtons

• Pressure exerted by the motorcycle on the road = P = 120 Pascals

To find :

• Surface area of the tyre which is in contact with the road

Formula :

• Pressure = Force/Area

Substituting the values :

120 = 1200/Area

120×Area = 1200

Area = 1200/120

Area = 10 m²

The area of the tyre in contact with the road is equal to 10 m²

More :

Si unit of pressure = pascals

Si unit of force = Newtons

Si unit of surface area = m²

Answer 2

✰ Given -

• Force (F) = 1200 Newton
• Pressure (p) = 120 Pascal's

✰ To Find -

• Surface Area of Tyre

✰ Solution -

We know Formula for Pressure,

$✓ \: </strong><strong>P</strong><strong> = \frac{</strong><strong>F</strong><strong>}{</strong><strong>A</strong><strong>}$

Here,

• P = Pressure
• F = Force
• A = Acceleration

Placing Value,

$⟶120 = \frac{1200}{area}$

$⟶Area = \frac{\cancel{1200}}{\cancel{120}}$

$⟶Area = 10 {m}^{2}$

⛬ Area in contact with road is 10m^2
