Final answer:
The kinetic energy of a 10 kg toddler running at a speed of 5.0 m/s is 125 Joules, calculated using the formula KE = (1/2)mv². Therefore, the kinetic energy of the running toddler is 125 Joules.
Step-by-step explanation:
The energy referred to in this question is kinetic energy, which depends on both the mass of the object and its velocity. Kinetic energy (KE) is given by the formula KE = (1/2)mv², where 'm' is the mass and 'v' is the velocity. In this case, the mass of the toddler (m) is 10 kg and the velocity (v) is 5.0 m/s.
Let's calculate it: KE = (1/2) × 10 kg × (5.0 m/s)²
= (1/2) × 10 × 25
= 125 Joules.
Therefore, the kinetic energy of the running toddler is 125 Joules.
