5. Two objects collide head on. The first object of mass 1.8x10³ kg has initial speed +15 m/s, and the second object of mass 9.0x10²kg travels with speed -15 m/s. After collision they become entangled. Find the change in kinetic energy AEK: ..4.5 x10² J .2.7x105 J 6. ....14 J Will the same ship float higher in salt water than in fresh water? will float higher will not change will float lower ....... 2 7. How much will a pendulum period change when its length will increase 4-times? will increase 4-times will increase 2-times will decrease 2-times 5. Two objects collide head on.
