When a golf ball is hit, it travels at 41 m/s. The mass of the golf ball is 0.045 kg. What is the kinetic energy of the golf ball? Show all of your work.
The formula to calculate the kinetic energy (KE) of an object is:
KE = (1/2) * m * v^2
where m is the mass of the object and v is its velocity.
Given:
m = 0.045 kg
v = 41 m/s
Plugging the values into the formula, we get:
KE = (1/2) * 0.045 kg * (41 m/s)^2
Calculating the square of the velocity:
KE = (1/2) * 0.045 kg * (1681 m^2/s^2)
Simplifying:
KE = 0.5 * 0.045 kg * 1681 m^2/s^2
KE = 37.7625 J
Therefore, the kinetic energy of the golf ball is 37.7625 Joules.
