Let a particle moves in space so that at time tt its position is stated as x=2t+3,y=t2+3t,z=t3+2t2.x=2t+3, y=t^2+3t, z=t^3+2t^2.

Let us find the components of its velocity:

vx=x=2,vy=y=2t+3,vz=z=3t2+4t.v_x=x'=2, v_y=y'=2t+3, v_z=z'=3t^2+4t.

Let us find the components of its acceleration:

ax=x=0,ay=y=2,az=z=6t+4.a_x=x''=0, a_y=y''=2, a_z=z''=6t+4.

When t=1t=1 the components of its velocity are vx=2,vy=5,vz=7v_x=2, v_y=5, v_z=7 and the components of its acceleration are ax=0,ay=2,az=10.a_x=0, a_y=2, a_z=10.
