Answer :
Final answer:
The kinetic energy of a 160 g ball moving at a speed of 46.5 m/s is 174.045 Joules. This is calculated using the kinetic energy formula: 0.5 * mass * speed².
Explanation:
The kinetic energy (KE) of an object can be calculated using the formula: KE = 0.5 * m * v², where m is the mass of the object and v is its speed. In this case, the mass (m) of the ball is 160 g, which is 0.16 kg when converted to kilograms. The speed (v) of the ball is given as 46.5 m/s.
Substituting the given values into the formula, we get:
KE = 0.5 * 0.16 kg * (46.5 m/s)² = 174.045 Joules
Therefore, the kinetic energy of the ball is 174.045 joules.
