The kinetic energy (KE) of an object is given by the formula:
KE = 1/2 * m * v^2
where m is the mass of the object and v is its velocity.
Given:
mass, m = 150 g = 0.15 kg (converting to kg)
velocity, v = 15 m/s
Substituting these values in the formula, we get:
KE = 1/2 * 0.15 kg * (15 m/s)^2
KE = 1/2 * 0.15 kg * 225 m^2/s^2
KE = 16.875 J (joules)
Therefore, the kinetic energy of the object is 16.875 joules.
