Question

road A and road B have the slopes of 1 and 1/2,respectively. suppose that two road will lead you to the same destination,ideally which road will you choose if your bus is carrying 50 passenger

Answer 1

If my bus is carrying 50 passengers, I would prefer to choose the road with less slope i.e road B with 1/2 slope

• By drawing FBD of the given situation, we can see that N = mg.cos(theta)
• Also, we know that cos is a decreasing function, so with an increase in theta cos value will decrease
• If the cos value decreases, the value of N i.e normal also decreases
• Lesser the value of normal reaction, more is the chance of bus to get topple from the road.
