Question

A 2kg toy robot dog walking at 2m/s
calculate the kenetic energy

Answer 1

Step-by-step explanation:

To calculate the kinetic energy of the toy robot dog, we can use the formula:

Kinetic Energy = (1/2) * mass * velocity^2

Since the mass of the toy robot dog is 2 kg and the velocity is 2 m/s, we can substitute these values into the formula:

Kinetic Energy = (1/2) * 2 kg * (2 m/s)^2

= (1/2) * 2 kg * 4 m^2/s^2

= 2 kg * 2 m^2/s^2

= 4 Joules

Therefore, the kinetic energy of the toy robot dog is 4 Joules.

Answer 2

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.
