The answer explains deceleration, distance traveled during deceleration, and the use of acceleration equations to solve related problems.
Deceleration: Deceleration is the rate at which an object slows down. It is calculated as the negative acceleration. In the given scenario, the train's deceleration can be calculated by dividing the initial velocity (75 km/h) by the time taken to stop (1.5 minutes).
Distance: To find the distance traveled during deceleration, you can use the kinematic equation: distance = initial velocity time + 0.5 acceleration * time^2.
Acceleration Equations: Kinematic equations such as v² = u² + 2as can be used to solve problems related to acceleration and deceleration in physics.
