Answer:
The dog has more momentum than the pony.
Explanation:
To solve this problem, we must remember the formula for calculating momentum, which is given below:
momentum = p = m*v
where m represents the mass of the object and v represents the velocity of the object
Using this knowledge, let's calculate the momentum for the dog and the pony.
Dog: p = m*v = (2kg)*(41 m/s) = 82 kg*m/s
Pony: p = m*v = (75kg)*(1 m/s) = 75 kg*m/s
Since 82 > 75, we can conclude that the dog has more momentum.
Hope this helps!
Answer:

Explanation:
From the question we are told that:
Mass 
Height 
Speed 
Angle 
Generally the equation for K.E is mathematically given by
Since
The potential energy and kinetic energy is equal to the kinetic energy as it hits the ground.
Therefore



Visibly you can see that the two copper are different sizes so the mass and volume are different. No information is given about the temperature but they are side by side so you can assume they're both room temp. The density is a ratio of mass per volume. The density will remain the same unless the two are different purities or physical states.
Answer:
Thermal energy
Explanation:
The thermal energy associated with the random motions of the atoms or molecules.
When the temperature of the substances rise then their molecule starts to vibrate within the system and the energy associated with the vibration of the molecule is known as thermal energy.The responsible factor for the rise in temperature is thermal energy.
Therefore answer is --
Thermal energy
If the coordinates of the initial point and the end point of a vector is given, the Distance Formula can be used to find its magnitude. resultant force is the force (magnitude and direction) obtained when two or more forces are combined.
