Answer:
The final velocity of 18 kg ball is = 42.09
Explanation:
Mass of first ball = 18 kg
Mass of second ball = 47 kg
Initial velocity of 18 kg ball = 76
Initial velocity of 47 kg ball = 0
Final velocity of 18 kg ball = ??
Final velocity of 18 kg ball is given by the formula
=
Put all the values in above formula we get
= 2 × 18 ×
= 42.09
Thus, the final velocity of 18 kg ball is = 42.09
