Homework Statement
A plane lands with a speed of 80.0 m/s and can accelerate with a maximum magnitude of 6.00 m/s^2 as it comes to rest. From the instant the plane touches the runway, what is the minimum time interval needed before it can come to rest?
b. what is the minimum distance the plane requires to land?
Homework Equations
vxf-vxi=integral o to t axdt
vxf=vxi+axt
d=(vi+vf/2)t
The Attempt at a Solution
a. vi=80.0m/s
vf=0m/s
a=6.00 m/s^2
Is this right so far?
Would I then use the formula vxf=vxi+axt and solve for t?
b. d=(vi+vf/2)t
Now I just need to solve for d, right?
Thank you very much
