(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

There are two questions.

1) A baseball, m=0.045 kg, moves in +y-direction with v = 5 m/s. a tennisball is moving in the -x direction with speed of 2m/s. Wat is the magnitude and direction of total momentum in the system?

2) A 0.01 kg rifle bullet is fired with v = 500 m/s into a ballistic pendulum of mass 5 kg suspended from a cord 0.6 m long. Find the height of the pendulum, the initial kinetic energy of the bullet and the kinetic energy of the bullet and pendulum.

3. The attempt at a solution

1) I have no idea, beside finding the momentum of the each balls.

2) I tried using p_bullet + p_pendulum = (m_bullet + m_pendulum)u, but I get u = 0,998 m/s, which i believe is incorrect.
