Suppose a particle of mass 3kg moves under the influence of a force F newten The velocity of the particle is given by
v =(1-sin 2t)i+(-1+cos 2t)j , v m\s
Find F ,and F is constant or not

You might like to try differentiating , then using This gives you as a function of . Is it constant or does it vary with ?

thank you but if

then

That tells you that the magnitude of the force is constant, but the force itself is not.

Yes I have some turbulence
Is the force constant or variable

It is variable, because its vector components each depend on .
