Question

uh.. "if p+q= 12 and pq= 2 then find p^2+q^2

Answer 1

The Conservation of Momentum Principle

The principle of conservation of momentum states that in an isolated system, two objects that collide have the same combined momentum before and after the collision. That is, momentum is not destroyed in the collision, but transferred between the two objects. In an isolated system, momentum is always conserved in a collision. In the example of you catching a baseball, the momentum from the ball is transferred into your hand.

How momentum is transferred depends on the type of collision. There are three types of collisions: elastic, perfectly inelastic, and partially inelastic

Answer 2

Answer:

Step-by-step explanation:

(p+q)^2=p^2+2pq+q^2

(p+q)^2=144

p^2+2pq+q^2=144

p^2+2(2)+q^2=144

p^2+q^2+4=144

p^2+q^2=140
