4. A jet plane traveling at 88 m's lands on a runway and is decelerated (negative acceleration) to rest in 11.0 seconds.
(a) Calculate the plane's acceleration?

(b) Calculate the distance the plane travels during the 11.0 s.

Discard my wrong work lol

An object's buoyant force and weight mean the same thing.a. trueb. false

Positrons are spontaneously emitted from the nuclei of

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
