1. What is the velocity of a 0.7 kg ball that has a momentum of 1.4
?
(Note: To solve problem no.1, use the momentum triangle formula.)
2. An object having a mass of 10 kg has its velocity change from 8 m/s east to 3 m/s east. Findthe object’s change in momentum?
3. Consider the perfectly elastic collision between two balls of masses 120g (m1) and 240g (m2). If ball 1 is moving with a velocity of 32.0 cm/s to the right and ball 2 with a velocity of 25.0 cm/s in the same direction. Find the velocity of ball 1, if ball 2 has a final velocity of 28.0 cm/s.
