Radius vector of a particle moving on a circle is given by r=2cos2t i+2sin2t j. The speed of particle is (where r is in m and t is in s)

A particle is moving in X-Y plane that x=2t and y=5sin(2t). Then maximum speed of particle is:

The displacement of a particle moving in a straight line, is given by s = 2t^2 + 2t + 4 where s is in metres and t in seconds. The acceleration of the particle is.

Position vector of a particle moving in space is given by : vec(r)=3sin t hat i+3 cos t hatj+4 t hatk Distance travelled by the particle in 2s is :

IF the equation for the displancement of a particle moving on a circular path is given by theta=2t^3+0.5 , where theta is in radius and t is in seconds, then the angular velocity of the particle at t=2 s is

The position vector of a particle is r = a sin omega t hati +a cos omega t hatj The velocity of the particle is

A particle moves in a circle of radius 20 cm . Its linear speed is given by v = 2t where t is in seconds and v in m s^-1 . Then

The speed of a particle moving in a circle of radius r=2m varies witht time t as v=t^(2) , where t is in second and v in m//s . Find the radial, tangential and net acceleration at t=2s .

The kinetic energy of a particle moving along a circle of radius R depends on the distance covered s as T=as^2 , where a is ticle as a function of s.
