Question

A cricket ball of mass 100 g has an initial velocityū = (2+3j
) m's and a final velocity v=-(2î+3ị) mis after being hit by bat. The change
in momentum (in kg m s) of the ball is
O-(0.31 +1:21)
O-(0.41 +0.63
0 - (4i +6] )
Zero​

Answer 1

Answer:

1/10[-(4i+6j) ]

Explanation: change in momentum= m(vf-vi)

100/1000[-(2i+3j) -(2i+3j) ]

= 1/10[-(4i+6j) ]
