To solve this, we are going to use the formula for the kinetic energy of an object:
where
is the kinetic energy of the object.
is the mass of the object.
is the speed of the object.
We know form our problem that the mass of the horse is 500 kilograms, so
; we also know that the speed of the horse is 5 meter/second, so
. Lets replace those values in our formula to find
:
J
We can conclude that the kinetic energy of the horse is
6250 Joules.
Answer:
The displacement is 20 m northward.
The distance is 44 m
Explanation:
Let northward motion be in positive direction
Let southward motion be in negative direction
Dispalcement is the shortest path covered by the hockey puck at a specified direction.
The dispalcement of the hockey puck will be calculated as;
Displacement = 26 m northward - 12m southward + 6 m northward
Displacement = 20 m in northward direction
Distance is the total path covered by the hockey puck.
Distance = 26 m + 12m + 6 m
Distance = 44 m
The statement '<span>The more particles a substance has at a given temperature, the more thermal energy it has' is true. </span><span>The
kinetic molecular theory of gases has three main laws and one of them is the
average kinetic energy of the particles in a gas. The average kinetic energy of
the gas particles is the behavior and movement it does in the surroundings. It
is directly proportional to temperature wherein if you increase the
temperature, the kinetic energy of a particle also increases. It will also
decrease its movement or its kinetic energy if the temperature lowers. </span>
Because real electrons are in an electron cloud, not layers
2.1 x 102
Is the correct solution for this problem
