Answer 1

Hii buddy

Answer:

In order to solve the question, first assume the mountain as a triangle... With lateral sides as 8 and 5 km.

In the both the cases the surface is same, i. e. The coefficient of friction is constant,

So, the frictional force in both the cases will be same, and mass of the bicycle and the man is also constant...

Now, we know that the angle opposite to the larger side is larger than that to the smaller one..

Therefore, the 5 km path will be easier to travel..

Hope it helps you.

Follow me.

Answer 2

Answer:

simple answer has an assumption that gradient of constant.in that case a 8km long road will have a less steep slope compare to a 5km long road.A cyclist will find it easier to ride the longer but less steep road.
