A 4.0-kg mass has a velocity of 4.0 m/s, east when it explodes into two 2.0-kg masses. After the explosion one of the masses has a velocity of 3.0 m/s at an angle of 60 north of east. What is the magnitude of the velocity of the other mass after the explosion?
 a. 7.9 m/s
  b. 8.9 m/s
  c. 7.0 m/s
  d. 6.1 m/s
  e. 6.7 m/s

Question 2

A 5.0-kg mass with an initial velocity of 4.0 m/s, east collides with a 4.0-kg mass with an initial velocity of 3.0 m/s, west. After the collision the 5.0-kg mass has a velocity of 1.2 m/s, south. What is the magnitude of the velocity of the 4.0-kg mass after the collision?
 a. 2.0 m/s
  b. 1.5 m/s
  c. 1.0 m/s
  d. 2.5 m/s
  e. 3.0 m/s
