Question

A particle moves in a straight line with an acceleration which is proportional to its velocity. The particle
has a velocity of 20 m/s when it passes through O, a fixed point on the line, and a velocity of 4 m/s
when its displacement from O is 4m. Show that subsequently the particle is always less than 5 m from
0.​

Answer 1

Answer:

moves along a circular track with constant tangential acceleration of 0.28 m/s2. It

starts at rest from a point A. Find the velocity and acceleration components of the particle along

x and y directions when it reaches point B. Radi is 2m & theeta is 20degres.
