A 10.0-kg animal is running at a rate of 3.0 m/s. What is the kinetic energy of the animal? (1 point) a. 3.3 J b. 30.0 J c. 45.0 J d. 90.0 J
KE = 1/2 mv^2 = 1/2 * 10 * 3^2 = _____
To calculate the kinetic energy of an object, you can use the formula:
Kinetic Energy = (1/2) * mass * velocity^2
In this case, the mass of the animal is given as 10.0 kg, and the velocity is 3.0 m/s.
Substituting these values into the formula:
Kinetic Energy = (1/2) * 10.0 kg * (3.0 m/s)^2
Calculating this expression:
Kinetic Energy = (1/2) * 10.0 kg * 9.0 m^2/s^2
Simplifying:
Kinetic Energy = 45.0 kg * m^2/s^2
So, the kinetic energy of the animal is 45.0 Joules (J), which corresponds to option c. 45.0 J.
