When dealing with radioactive waste, the waste is put into a secret container.
In a well-sealed bucket, and then throw it into 300 inches of water.
With feet in the sea, will this practice cause radioactive pollution?
Dyeing?
The crux of the problem is: how fast can the drum be played?
What is the speed when the drum collides with the seabed?
Experimental results: The speed of the drum in a straight line is 40 feet per second.
Will break under the impact of ...
Barrel capacity: 55 gallons (1 gallon =3.7854 liters)
The barrel full of radioactive waste weighs G=527.436 pounds.
Buoyancy: F=470.327 lbs.
Resistance: f = c v, c = 0.08.
Establish differential equation according to Newton's second law: (vertical
Linear coordinates)
From v(0)=0:
Limit speed: (86. 7 13) (lim second leg = ∞ >? C
Then find the speed at which the drum reaches the bottom of the sea.
