For any particle moving with some velocity `(vecv)` & acceleration `(veca)`, tangential acceleration & normal acceleration are defined as follows.
Tangential acceleration - The component of acceleration in the direction of velocity.
Normal acceleration - The component of acceleration in the direction perpendicular to velocity.
If at a given instant, velocity & acceleration of a particle are given by .
`vecc=4hati +3hatj`
`vaca=10hati+15hatj+20hatk`
Find the tangential acceleration of the particle at the given instant :-
A. `17(4hati+3hatj)`
B. `(17)/(5)(4hati+3hatj)`
C. `17(4hati-3hatj)`
D. `(17)/(5)(4hati-3hatj)`
