Question
Explain why passengers are thrown forward from their seats when a speeding bus stops suddenly.
Solution
When a speeding bus stops suddenly, passengers are thrown forward from their seats because their bodies are still moving forward at the same speed as the bus was traveling. This occurs due to the inertia of motion. While the feet of the passengers, which are in contact with the floor of the bus, stop along with the bus, the upper body continues to move forward. As a result, passengers fall forward.

In figure, a body A of mass m slides on plane inclined at angle θ1 to the horizontal and µ1 is the coefficent of friction between A and the plane. A is connected by a light string passing over a frictionless pulley to another body B, also of mass m, sliding on a frictionless plane inclined at angle θ2 to the horizontal. Which of the following statements are true?
- A will never move up the plane.
- A will just start moving up the plane when `µ = (sin θ_2 - sin θ_1)/(cos θ_1)`
- For A to move up the plane, θ2 must always be greater than θ1.
- B will always slide down with constant speed.
