The problem that follow involve straight-line motion. The time t is in seconds unless otherwise stated.
Problem
At the instant shown, the magnitude of the airplane's velocity is 130 m/s. its tangential component of acceleration is d1= –4 m/s2, and the rate of change of its path angle is dθ/dt = 5°/s.
(a)What are the airplane’s velocity and acceleration in terms of normal and tangential components?
(b) What is the instantaneous radius of curvature of the airplane’s path?
