Answer:
Kinetic energy possessed by the object is 120 J.
Explanation:
Given,
An object of mass = m = 15 kg
Uniform velocity = v = 4m s-¹
To find: what is the kinetic energy possessed by the object.
Solution:
Kinetic energy is defined as the energy of the body by virtue of its motion.
Kinetic Energy is directly proportional to the square of velocity.
i.e K.E = 1 / 2 mv²
here, m = 15 kg and v = 4 m/s
Substituting values, we will get,
K.E = 1/2 * 15 * 4 * 4
K.E = 120 J
Therefore, kinetic energy possessed by the object is 120 J.
