In this problem, we are required to calculate the time elapsed before a decelerating object comes to rest and the distance covered before stopping given its initial velocity, v0 and the deceleration, -a.
This is a Kinematics problem since it involves initial velocity, v0, acceleration, a, distance covered, Δx, and time, t.
We'll follow the following simple steps!
We need to remember the four kinematic equations in order to solve the problem. These are:
A certain jet comes in for a landing on solid ground with a speed of 100 m/s and its acceleration can have a maximum magnitude of 5.00 m/s2 as it comes to rest.
(a) From the instant the jet touches the runway, what is the minimum time interval needed before it can come to rest?
(b) Can this jet land at a small tropical island airport where the runway is 0.800 km long?
