What is the kinetic energy of a baseball moving at a speed of 40m/s if the baseball has a mass of 0.15 kg?
The formula for kinetic energy is given by:
Kinetic energy (KE) = (1/2) * mass * velocity^2
Given:
Mass (m) = 0.15 kg
Velocity (v) = 40 m/s
Plugging in the values:
KE = (1/2) * 0.15 kg * (40 m/s)^2
Calculating:
KE = (1/2) * 0.15 * (1600)
KE = 0.5 * 0.15 * 1600
KE = 120 joules
Therefore, the kinetic energy of the baseball moving at a speed of 40 m/s is 120 joules.
