Two different masses are dropped from same heights, then just before these strike the ground, the following is same :a)Kinetic energyb)Potential energyc)Linear momentumd)AccelerationCorrect answer is option 'D'. Can you explain this answer?

Question

Answer

Both the objects with different masses will attain the same v when striking the ground because acceleration and height is the same.
As, K.E=(1/2)mv²P.E=−GMmp/r=mv
Thus K.E, P.E, and p will be different.

Answer

Accerelation mass pe depend nhi karta h.isliye acceleration hi answer hoga baki potential energy and kinetic energy change hoti h...

Answer

Because acceleration is independent of mass

Answer

They have the same acceleration g downwards because acceleration is independent of mass

Answer

Kinetic Energy:
When an object is in motion, it possesses kinetic energy. Kinetic energy is given by the formula KE = 1/2 mv^2, where m is the mass of the object and v is its velocity.

When the two different masses are dropped from the same height, they will have different velocities just before they strike the ground. Therefore, their kinetic energies will not be the same.

Potential Energy:
Potential energy is the energy possessed by an object due to its position or state. In the case of an object dropped from a height, it possesses potential energy due to its height above the ground. Potential energy is given by the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object above the ground.

Since both masses are dropped from the same height, their potential energies just before they strike the ground will be the same. This is because the mass and height are the same for both objects.

Linear Momentum:
Linear momentum is the product of an object's mass and its velocity. It is given by the formula p = mv, where p is the linear momentum, m is the mass of the object, and v is its velocity.

Since the two different masses will have different velocities just before they strike the ground, their linear momenta will not be the same.

Acceleration:
Acceleration is the rate of change of velocity with time. It is given by the formula a = (vf - vi) / t, where a is the acceleration, vf is the final velocity, vi is the initial velocity, and t is the time taken.

When an object is dropped from a height, it experiences a constant acceleration due to gravity, which is approximately 9.8 m/s^2. This acceleration is the same for all objects regardless of their mass. Therefore, just before the objects strike the ground, their accelerations will be the same.

Conclusion:
In conclusion, just before the two different masses strike the ground, their kinetic energies, potential energies, and linear momenta will not be the same. However, their accelerations will be the same since they experience the same acceleration due to gravity.
