(II) Calculate the forces and that the supports exert on the diving board of Fig. 9-42 when a person stands at its tip. (a) Ignore the weight of the board. (b) Take into account the board's mass of . Assume the board's is at its center.

Step 1 of 3 The impulse is large force acts on a body in short interval of time We know that p F t p F =k t where kis proportional constant its value is 1 F = mv because linear momentum p=mv t mv F = t here m is constant F t=mv F t=p where p=p -f i J = p -p f i J =mv- mu This theorem is called as impulse momentum theorem
