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

1000 meters, 200 meters

Explanation:

Given: Vi = 100 m/s and a = -5 m/s^2

From uniformly accelerated equation:  v = Vi + a t

then substitute

0 = 100 -5 t

t = 20 seconds

to go from 100 to 0 at -5m/s^2

d = Vi (20) - (1/2)(5)(20)^2

d = 100 (20) - 2.5(400)

= 2000 - 1000

= 1000 meters to stop, runs 200 meters beyond the end of the runway into the harbor where he strikes a passenger ferry.

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
