If a 35 kg zombie runs at a speed of 3.0 m/s. What is the zombie's kinetic energy?
a
315 J
b
105 J
c
53 J
d
158 J
The formula for kinetic energy is:
KE = 1/2 * m * v^2
Where:
KE = kinetic energy
m = mass (35 kg)
v = speed (3.0 m/s)
Plugging in the values into the formula:
KE = 1/2 * 35 kg * (3.0 m/s)^2
KE = 0.5 * 35 kg * 9 m^2/s^2
KE = 0.5 * 315 kg*m^2/s^2
KE = 157.5 J
Therefore, the zombie's kinetic energy is 157.5 J, which is closest to option d (158 J).
