what is the KE of a 6 kg mass at 4 m/s
what is 1/2 mass*velocity^2 ?
To calculate the kinetic energy (KE) of an object, you can use the formula KE = ½ * m * v^2, where m represents the mass of the object and v represents its velocity or speed.
In this case, you have a 6 kg mass moving at 4 m/s. Using the formula, you can calculate the KE as follows:
KE = ½ * 6 kg * (4 m/s)^2
= ½ * 6 kg * 16 m^2/s^2
= 48 Joules
Therefore, the kinetic energy of a 6 kg mass moving at 4 m/s is 48 Joules.
