Hi, I didn’t understand too well your question, but I hope this helps!
Archimedes principle is based on the weight of the object to push the object upward. Law of floation is the priciple which tells us about the density of the object with the liquid in which it is placed.
Answer: 30 metres
Explanation:
Initial velocity of object = 120m/s
Time taken = 4.0s
Distance covered by object = ?
Recall that distance = (Change in velocity / Time taken)
Distance = (120m/s)/4.0s
= (120m/s) / 4.0s
= 30m
Thus, the object will be 30 metres high
Force = mass * acceleration
F = 15 *8 = 120 Newton
