The kinetic energy (KE) of the mass can be calculated using the formula:
KE = (1/2) * m * v^2
Where m is the mass of the object and v is its velocity.
Substituting the given values:
KE = (1/2) * 4kg * (5m/s)^2
KE = (1/2) * 4kg * 25m^2/s^2
KE = 50 Joules
Therefore, the kinetic energy of the 4kg mass is 50 Joules.
KE = (1/2) * m * v^2
Where m is the mass of the object and v is its velocity.
Substituting the given values:
KE = (1/2) * 4kg * (5m/s)^2
KE = (1/2) * 4kg * 25m^2/s^2
KE = 50 Joules
Therefore, the kinetic energy of the 4kg mass is 50 Joules.
