What is the formula for the vertical component of a momentum $p$?? $$ p\sin\theta $$
What is the formula for the horizontal component of a momentum $p$?? $$ p\cos\theta $$
If an object with mass $m_1$ is travelling in a straight line with velocity $v_1$, what is its momentum?? $$ m_1v_1 $$
If an object with mass $m_1$ is travelling at an angle $\theta_1$ to the $x$ direction with velocity $v_2$, what is its momentum?? $$ m_1v_1\cos\theta_1 $$
