A car is travelling with linear velocity (v) on a circular road of radius (r). If it is increasing its speed at the rate of a ( mt//sec^(2) ), then the resultant acceleration will be

If a particle moves in a circle of radius 4m at speed given by v = 2t where v is in m/s and t in sec at t = 4sec, acceleration of particle will be

A conic section is defined by the equations x=-1+sec t,y=2+3 tant . The coordinates of the foci are

If a man has a velocity varying with time given as v=3t^(2),v is in m//s and t in sec then : Find out the velocity of the man after 3 sec .

If a man has a velocity varying with time given as v=3t^(3),v is in m//s and t in sec then : Find out the velocity of the man after 4 sec .

If a man has a velocity varying with time given as v=3t^(2),v is in m//s and t in sec then : Find out the velocity of the man after 3 sec .

If x = 3 tant and y = 3 sec t, then the value of (d^2y)/(dx^2)" at" t=pi/4 is
