2. A 220 g ball travelling East with a velocity of 4.2 m/s, collides with a 300 g ball at rest. A glancing collision occurs and the ball that was at rest is now moving with a velocity of 2.1 m/s [E 40ᵒ S].
Determine the velocity (and direction) of the other ball. [6]

For question 2 above determine whether kinetic energy was conserved and explain by citing the type of

collision. [4]

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
