Answer:
12.25m/s
Explanation:
Since the initial velocity of the dropped rock is 0, you can write this as:
Now, you can set up the equation for the thrown rock:
Hope this helps!
The rate at which an object moves is called speed or velocity depending if the direction does or doesnt matter
The ability of solid rock to flow is called Plasticity.
Plasticity is the deformation of a solid mateial which resulted in non reversible changes of shape in response to applied force.
Another example of plasticity is when you bend metal through a forcer force to create an art or kitchen set
Explanation:
Fgravity = G*(mass1*mass2)/D².
G is the gravitational constant, which has the same value throughout our universe.
D is the distance between the objects.
so, if you triple one of the masses, what does that do to our equation ?
Fgravitynew = G*(3*mass1*mass2)/D²
due to the commutative property of multiplication
Fgravitynew = 3* G*(mass1*mass2)/D² = 3* Fgravity
so, the right answer is 3×12 = 36 units.
