if graph of velocity v and time t for a particle moving along straight line is parabola symmetric about time axis, then the relation between acceleration a and time t for particle is …. ? (Divya posted this question)
A Few Problems from Kinematics
A body falling freely from rest has velocity v after it falls a height h . Calculate the distance it should fall down further for its velocity to become double A particle in uniform acceleration in a straight line has a speed of v m/s at position x meter is given by √(25-16x). What is [...]
