Answer:
for X, it's 50 times cos 35.
for y, it's 50 times sin 35.
Explanation:
Since the bottle of water was inside the refrigerator, it is cooler than the air outside the refrigerator.
There is water vapour in the air which gets cooled by the bottle and changes state from gas to liquid and settles on the bottle.
here we can use energy conservation
like initial kinetic + potential energy is always conserved and it will be same at all points
so we can say
now we can plug in all the given values in it
now divide whole equation by mass "m"
so final speed will be 65.96 m/s
