Radius of gyration is defined as the distance from the axis of rotation to a point where the total mass of the body is supposed to be concentrated, so that the moment of inertia about the axis may remain the same. Simply, gyration is the distribution of the components of an object.

x(t)= 3t+4t^2+5t^3. dx/dt= 3+8t^1+15t^2=v. dv/dt= 8+30t^1 =a. Here, a= 8+30×2^1=68 Force= mass × accelaration. Force=mass×68 N.

Projectile Motion equation derivation – parabola The velocity component along X axis = V0x = V0 cosθ and the velocity component along Y axis = V0y = V0sinθ. Air resistance is taken as negligible. In the above equation g, θ and V0 are constant. ... y = ax + bx2 where a and b are constants.
