Answer:
Step-by-step explanation:
To calculate the kinetic energy of the toy robot dog, we can use the formula:
Kinetic Energy (KE) = 0.5 * mass * velocity^2
where:
mass = 2 kg (mass of the toy robot dog)
velocity = 2 m/s (velocity of the toy robot dog)
Now, let's plug in the values and calculate the kinetic energy:
KE = 0.5 * 2 kg * (2 m/s)^2
KE = 0.5 * 2 kg * 4 m^2/s^2
KE = 4 kg m^2/s^2
The units of kinetic energy are typically expressed in joules (J). So, the kinetic energy of the 2 kg toy robot dog walking at 2 m/s is 4 joules.
