Final answer:
The kinetic energy of a 1.5 kg bowling ball moving at 9 m/s is 60.75 Joules.
Step-by-step explanation:
The formula to calculate the kinetic energy of an object is KE = 1/2 * mv^2, where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object.
In this case, the mass of the bowling ball is given as 1.5 kg and the velocity is given as 9 m/s.
Using the formula, we can calculate the kinetic energy as follows:
KE = 1/2 * 1.5 kg * (9 m/s)^2
KE = 1/2 * 1.5 kg * 81 m^2/s^2
KE = 60.75 J
Therefore, the bowling ball has a kinetic energy of 60.75 Joules when moving at a velocity of 9 meters per second.
