Step-by-step explanation:
Hello!
Remember that kinetic energy is one that is produced by the speed of a body that has mass. The equation is as follows.
Where
E=kinetic energy
m=mass
V=speed
To solve this problem we must raise the equation for the kinetic energy of the sphere and the kinetic energy of the cylinder.
for cilinder
for spherical shell
as the problem indicates the kinetic energy is the same, so we can match the previous equations
according to the problem the masses are equal Ms = Mc
we apply square root on both sides of the equation
In conclusion, if two bodies, regardless of their shape, have the same mass and the same kinetic energy, the speed of the two bodies will be the same.
