Solution: Suppose two asteroids strike head on. Asteroid A ( exttip{m_{
m A}}{m_A}8.1×1012 kg) has velocity 3.6 km/s before the collision, and asteroid B (exttip{m_{
m B}}{m_B}1.6×1013 kg) has velocity 1.3 km/s before the collision in the opposite direction.(a) If the asteroids stick together, what is the magnitude of the velocity of the new asteroid after the collision?(b) What is the direction of the velocity of the new asteroid after the collision?

Suppose two asteroids strike head on. Asteroid A ( 8.1×10^{12} kg) has velocity 3.6 km/s before the collision, and asteroid B (1.6×10^{13} kg) has velocity 1.3 km/s before the collision in the opposite direction.

(a) If the asteroids stick together, what is the magnitude of the velocity of the new asteroid after the collision?

(b) What is the direction of the velocity of the new asteroid after the collision?
