चाल तथा वेग Class 11 Physics | सरल रेखा में गति -L2 | Motion in A Straight Line | Speed and Velocity

Three particles start from origin at the same time: one with velocity v^(1) along positive x-axis, the second along the positive y-axis with a velocity v^(2) and the third along the line y = x with such a speed that all the three always stay in a straight line, then velocity of the third particles is:

Assertion: For a particle moving in a straight line velocity (v in m//s) of the particle in terms of time (t in sec) is given by v = t^2 - 6t + 8 . Then the speed of the particle is minimum at t = 2 sec Reason: For a particle moving in a straight line line velocity v at any time t may be minimum or may be maximum when (dv)/(dt) = 0 .

if a=3t^(2)+2t , initial velocity is 5 m//s . Find the velocity at t=4s. The motion is in straight line, a is acceleration in m//s^(2) and t is time in seconds.

If the distance y of a point moving on a straight line measured from a fixed origin on it and velocity v are connected by the relation 4v^(2)=25-y^(2) , then show that the motion is simple harmonic and find its time period.

A particle retards from a velocity v_(0) while moving in a straight line. If the magnitude od deceleration is directly proportional to thesquare roop of the speed of the particle, find its average velocity for thetotal tome of ist motion.
