Since action and reaction are always equal in magntiude and opposite in direction, how can anything ever be accelerated?

Action and reaction are always ____ and ___.

What happens when force acting on an object are in opposite direction and equal?

If action is always equal to reaction, explain how a horse can pull a cart ?

Can the velocity of an object be in a direction other than the direction of acceleration?

In the figure gives a speed-time graph of a particle in motion along a constant direction. Three equal intervals of time are shwon. In which interval is the average acceleration greatest in magnitude ? In which interval is the average speed greatest ? Choosing the positive direction as the constant direction of motion, give the signs of v and a in the three intervals. What are the acceleration at the points A,B,C and D?

Vertically opposite angles are not always equal.

Can a body have acceleration in one direction and velocity in another direction?
