Just plug in the values of v and t...that will give the magnitude of average acceleration
Answer:
The value speed is
Explanation:
From the question we are told that
The mass of the ping pong ball is
The radius is
The depth of the ping pong inside the water is
Gnerally the force with which the ball will emerge will from the water is mathematically represented as
Here B is the Buoyant force on the ball which is mathematically represented as
Here is the volume of the ball which is mathematically represented as
=>
=>
is the density of water with value
So
=>
So
=>
=>
Generally force is mathematically represented as
So
=>
Generally from kinematic equation
Here u is the velocity of the ping pong at depth of 0.3 m and the value is zero given that at that point there was no motion
So
=>
Neither object will float in water.
They both have densities greater than 1.0 g/cm³,
so both will sink to the bottom of the beaker.
Like rocks.
