A collision is an event where momentum or kinetic energy is transferred from one object to another. ...
There are two general types of collisions in physics: elastic and inelastic.
An inelastic collisions occurs when two objects collide and do not bounce away from each other.
An elastic collision occurs when the two objects "bounce" apart when they collide. Two rubber balls are a good example.

Sia ? 3 years, 10 months ago

In mathematics, a hyperbola is a type of smooth curve lying in a plane, defined by its geometric properties or by equations for which it is the solution set. A hyperbola has two pieces, called connected components or branches, that are mirror images of each other and resemble two infinite bows.

Sum of A.P. = T₁ + T₂ + T₃.....T
Given AP = a , T₂ , T₃....., ,b
Sum of Given A.P. =[ a+ (a+d)+(a+2d)+(a+3d)+..+(a+nd)]
A.P. = [(b-nd)+...+(b-3d)+(b-2d)+(b-d)+b]
By Adding both A.P. we get 2(A.P.) = na+nb + 0d
A.P. = n(a+b)/2
Sum of terms = ½n(a+b)
