Given:
speed of 0.40meters/seconds
1,800 Newton's horizontal force
Required:
Power of the horse
Solution:
P = F(D/T) where P is power in watts, F is the force, D is the distance and T is time
P = (1,800N) (0.40 meters/seconds)
P = 720 Watts
Answer:
Explanation:
The internal energy of any material is calculated as the sum of kinetic and potential energy of randomly distributed molecules.
This energy depends on temperature as well, if the temperature will increase the randomness will also increase hence will be the internal energy.
If any work is done on the system, then also the internal energy of the system is increased.
Explanation:
Carbon dioxide is a naturally occurring greenhouse gas... An increase in the amount of carbon dioxide creates an overabundance of greenhouse gases that trap additional heat. This trapped heat leads to melting ice caps and rising ocean levels, which cause flooding.
The kinetic energy of an object varies directly with the square of the speed of an object. The required kinetic energy of the shot is f 162 J.
The energy possessed by an object by its motion is known as the object's kinetic energy. It depends on the speed and mass of the given object.
Given data -
The mass of shot put is, m = 4 kg.
The speed of shot put is, v = 9 m/s.
The mathematical expression for the kinetic energy of the shot put is,
Solving as.
Thus, we can conclude that the required kinetic energy of the shot is of 162 J.

Answer:
We have: K.E. = mv² / 2
here, m = 4 Kg
v = 9 m/s
Substitute their values into the expression:
K.E. = (4)(9)² / 2
K.E. = (4)(81) / 2
K.E. = 324 / 2
K.E. = 162 Joules
Explanation:
In short answer: it would be K.E.=162 Joules
