Question

a motorcycle weighs 4,500 N if the pressure the tyres exert on the road is 1000000 pa , what is the area of each tyre in contact with the road ? ( remember that a motorcycle has two tyre )​

Answer 1

Answer:

4500N divided on two tyres is 2250N tyres each.

No, let's first take the whole thing ya?

Now, P = F/A 100000 = 4500/A

A = F/P

A = 4500/1000000

= 45/10000

= 4.5 x 10-³ (it is actually power of minus

three)

4.5 x 10-³m² total area in contact or 0.0045m²

each tyre = 0.0045/2

= 0.00225m² surface area of each tyre is in contact with the street.

STEP-BY-STEP EXPLANATION:-

F:–45OO

P:–1OOOOOO X 1O^6 P

P=F/A

A=45OO

------------------

1OOOOOO

A=4.5 x (1O)^-3

-----------------------

2

A=2.25 x (1O) ^-3
