Which falling object will result in the least kinetic energy when it collides with the ground?
The falling object that will result in the least kinetic energy when it collides with the ground is an object that has the lowest velocity.
According to the kinetic energy formula, KE = (1/2)mv^2, where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object.
Since the mass (m) is already given, the only way to minimize the kinetic energy is to minimize the velocity (v). Therefore, the object with the least kinetic energy when it collides with the ground is the one with the lowest velocity.
