Question

the velocity of a curling stone is due east. what will be the direction of the momentum of the curling stone as it moves?

Answer 1

east.
momentum = mass x velocity
the direction of the momentum is the same as that of velocity.

Answer 2

Answer: to east.

Explanation: Momentum is the "amount of movement" and can be written as:

P = m*v

where P is momentum, m is the mass of an object moving and v is the velocity of the object.

As you may know, the velocity is a vector and the mass is a scalar, so the momentum must be also a vector, that has the same direction that the vector of velocity, so if the velocity of the rock points to the east, also does the momentum.
