Answer :
Answer:
172 J.
Explanation:
The kinetic energy of an object is given by the formula:
KE = 0.5 * m * v^2
Where:
KE is the kinetic energy
m is the mass of the object
v is the velocity of the object
In this case, the mass of the bowling ball is 7 kg, and its velocity is 7 m/s. Plugging these values into the formula:
KE = 0.5 * 7 kg * (7 m/s)^2
KE = 0.5 * 7 kg * 49 m^2/s^2
KE = 171.5 J
Rounded to the nearest whole number, the kinetic energy of the ball is approximately 172 J. So, the answer is B) 172 J.
