Answer:
1.4719 m per sec
Explanation:
Hello
Kinetic energy is the energy associated with the movement of objects. Although there are many forms of kinetic energy
the formula to use is
where m is the mass of the object and v the velocity
lets see the kinetic energy of the sprinter running
Now, the elephant must have the same kinetic energy
it works only the positive root, so the elephant must to walk to 1.4719 m/s to have the same kinetic energy.
Have a great day
<span>A major characteristic of both volcanoes and earthquakes is that they are located in the same geographic area. Most earthquakes are along the edges of tectonic plates. This is where most volcanoes are too. Most earthquakes directly beneath a volcano are caused by the movement of magma.</span>
Answer:
Ball A will move towards West with speed 8 m/s
Ball B will move towards East with speed 12 m/s
Explanation:
As we know that during collision there is no external force on the system
So here we can use momentum conservation for finding the final velocities of two balls
so we have
since two balls are identical so we have
also we know that for elastic collision we have
so we have
so we have
Towards East
Towards West
