find the kinetic energy of an 8kg mass moving at 5m/s
The formula for kinetic energy is
(1/2) M V^2.
With M in kg and V in m/s, the answer will be in Joules.
Do the calculation
K.E = 40joule
To find the kinetic energy of a moving object, you can use the equation:
Kinetic Energy (KE) = 1/2 * mass * velocity^2
Given:
Mass (m) = 8 kg
Velocity (v) = 5 m/s
Plug in the values into the equation:
KE = 1/2 * 8 kg * (5 m/s)^2
Simplify the equation:
KE = 1/2 * 8 kg * 25 m^2/s^2
KE = 100 kg m^2/s^2
Therefore, the kinetic energy of an 8 kg mass moving at 5 m/s is 100 Joules (J).
To find the kinetic energy of an object, you can use the formula:
Kinetic energy (KE) = 1/2 * mass * velocity^2
In this case, you have an 8kg mass moving at 5m/s.
Substituting these values into the formula, we get:
KE = 1/2 * 8kg * (5m/s)^2
First, square the velocity term:
KE = 1/2 * 8kg * 25m^2/s^2
Then, multiply the mass and the squared velocity:
KE = 1/2 * 8kg * 25m^2/s^2
Next, simplify the equation:
KE = 100kg * m^2/s^2
Finally, determine the unit of measurement for kinetic energy, which is the Joule (J):
KE = 100 J
Thus, the kinetic energy of an 8kg mass moving at 5m/s is 100 Joules.
