Answer:
The lighter frog goes higher than the heavier frog.
The lighter frog is moving faster than the heavier frog
Explanation:
If both frogs have the same kinetic energy when they leave the ground, the following equality applies:
Now, if the only force acting on the frogs is gravity, when they reach to the maximum height, we can apply the following kinematic equation:
When h= hmax, the object comes momentarily to an stop, so vf =0
Solving for hmax:
As the lighter frog, in order to have the same kinetic energy than the heavier one, has a greater initial velocity, it will go higher than the other.
As a consequence of both having the same kinetic energy, the lighter frog will be moving faster than the heavier frog.
Answer:
54 kg
Explanation:
Mass of person = 93 kg =
Mass of water = 62 kg =
Dividing the above two masses we get
Hence, the mass of the person is 1.5 times the mass of the water in them
Now, Mass of person = 81 kg =
So, the mass of water in a person that has mass of 81 kg is 54 kg
Explanation:
In the picture.
I hope that it's a clear solution.
