A particle of mass `2 kg` moves in the `xy` plane under the action of a constant force `vec(F)` where `vec(F)=hat(i)-hat(j)`. Initially the velocity of the particle is `2hat(j)`. The velocity of the particle at time `t` is

An object of mass 2 kg at rest at origin starts moving under the action of a force vec(F)=(3t^(2)hat(i)+4that(j))N The velocity of the object at t = 2 s will be -

An object of mass 2 kg at rest at origin starts moving under the action of a force vec(F)=(3t^(2)hat(i)+4that(j))N The velocity of the object at t = 2 s will be -

A particle has initial velocity vec(v)=3hat(i)+4hat(j) and a constant force vec(F)=4hat(i)-3hat(j) acts on the particle. The path of the particle is :

A particle of mass 2kg moves with an initial velocity of (4hat(i)+2hat(j))ms^(-1) on the x-y plane. A force vec(F)=(2hat(i)-8hat(j))N acts on the particle. The initial position of the particle is (2m,3m). Then for y=3m ,

A particle moves in the x-y plane under acceleration vec(a) = 3hat(i) + 4hat(j) m//s^(2) . If the initial velocities is vec(u) = 6hat(i) + 8hat(j) m//s . Find the velocity and the position vector of a particle after 2 s .
