If a 35 kg zombie runs at a speed of 3.0 m/s. What is the zombie's kinetic energy?
No answer provided
a. 105 J
b. 315 J
c. 158 J
d. 53 J
The formula to calculate kinetic energy is K.E. = 1/2 * m * v^2, where m is the mass and v is the velocity.
Plugging in the values:
K.E. = 1/2 * 35 kg * (3.0 m/s)^2
= 1/2 * 35 kg * 9.0 m^2/s^2
= 1/2 * 315 kg * m^2/s^2
= 158 kg * m^2/s^2
Therefore, the zombie's kinetic energy is approximately 158 J. The answer is c. 158 J.
