The detailed answer explains how to calculate acceleration, distance traveled while braking, and deceleration in the context of the physics problem provided.
Acceleration: To calculate acceleration, we use the formula: acceleration = (final velocity - initial velocity) / time. In this case, the train goes from 18 km/h to 0 km/h in 10 seconds, which is a significant decrease in speed indicating deceleration.
Distance: To find the distance traveled while braking, we can use the kinematic equation: distance = (initial velocity + final velocity) / 2 * time. Plug in the values to get the distance covered while the train is braking.
Deceleration: When a train is braking, it is experiencing negative acceleration. The rate of deceleration can be calculated using the formula for acceleration, considering the change in velocity and time taken to stop.
