Answer:
Kinetic energy of dodgeball = 16 kg-m/s
Step-by-step explanation:
Given:
Mass of dodgeball = 2 kg
Velocity of dodgeball = 4 m/s
Find:
Kinetic energy of dodgeball
Computation:
Kinetic energy = (1/2)(m)(v²)
Kinetic energy of dodgeball = (1/2)(Mass of dodgeball)(Velocity of dodgeball²)
Kinetic energy of dodgeball = (1/2)(2)(4²)
Kinetic energy of dodgeball = (1/2)(2)(16)
Kinetic energy of dodgeball = (32/2)
Kinetic energy of dodgeball = 16 kg-m/s
