A jet plane lands with a speed of $100 \mathrm{m} / \mathrm{s}$ and can accelerate at a maximum rate of $-5.00 \mathrm{m} / \mathrm{s}^{2}$ as it comes to rest.(a) From the instant the plane touches the runway, what is the minimum time interval needed before it can come to rest? (b) Can this plane land on a small tropical island airport where the runway is $0.800 \mathrm{km}$ long?

Key Concepts

Deceleration

Deceleration refers to acceleration that decreases the speed of an object; it is represented by a negative value in the acceleration term. Understanding deceleration is crucial for determining how quickly a moving object can come to a stop, which is important in calculating stopping time and distance.

Stopping Time and Distance Calculation

This concept covers applying the constant acceleration equations to determine the minimum time required for an object to come to rest and the corresponding distance covered during this period. These calculations are key in safety assessments, such as verifying that an aircraft can stop within the available runway length.

Constant Acceleration Kinematics

This concept involves using the kinematic equations that relate displacement, velocity, acceleration, and time when the acceleration is uniform. Equations such as v = v? + at and x = v?t + 0.5at² allow one to compute the time required for an object to change its velocity and the distance it travels during that change.
