Answer:
The velocity of the composite body is 0.99m/s 63.43° west of north.
Explanation:
Here the law of conservation of energy says that
where is the final velocity if the composite body, and
is measured from west of north.
Putting in numbers and simplifying the above equation we get:
dividing equation (4) by (3) gives
putting in ,
,
, and
we get:
Thus, the final velocity we get from equation (3) is:
Thus, the velocity of the composite body is 0.99m/s 63.43° west of north.
