d

anonymous · Answer

Parik, please don't just hand out the answer. D is highly incorrect.

anonymous · Answer

Nyree, Velocity is the derivative of what 2 variables?

anonymous · Answer

velocity is vector 
its direction is changed 
lets say now it is in +ve x direction 
now if there is any problem u do with this situation reference is changed

not it is displaced or accelerate and neither frame is changed 
what u refer now is changed

anonymous · Answer

That's where you're wrong.  Displacement and time form the derivative velocity.  If a ball were to be rolling towards you in a forward notation and you applied positional force, changing the ball's displacement will indefinitely increase the derivative known as velocity.  In conclusion, the rational answer would be A.

anonymous · Answer

However, because it only applies to velocity as a vector, applying external, positional force, the ball's velocity would indefinitely increase (as amused in the previous premise).  Therefore, the correct answer is B.

yeah it is b
