centre of gravity can be define as the point through which
the line of action of the weight of the body always passes
irrespective of the position of the body .Naijacomms.com
12 b)
C . g = centre of gravity
: - v = u - gt
Of maximum height v = O - K
O = u - gt
For vertical component, U = uSin tita
Therefore O = usin tita - gt
gt =uSin tita
T = uSin tita / g
Where T is the time taken to maximum height
