# VC1.10

From Example Problems

Let r be the position vector of any point P(x,y,z) on the given curve at time t.Then, we have

Therefore, velocity=

Acceleration=

At t=1,

Unit vector in the direction of is

Therefore, Required component of velocity is the dot product of the velocity vector and the unit vector above.

Similarly,Required component of acceleration is the dot product of the acceleration vector and the unit vector above.
