a. 40 J
b. 50 J
c. 80 J
d. 100 J
Without waiting for a response
To calculate the kinetic energy of an object, you can use the formula:
Kinetic Energy = 0.5 * mass * velocity^2
Given:
Mass of the bowling ball = 5.0 kg
Velocity of the bowling ball = 4.0 m/s
Plugging these values into the formula:
Kinetic Energy = 0.5 * 5.0 kg * (4.0 m/s)^2
Simplifying:
Kinetic Energy = 0.5 * 5.0 kg * 16 m^2/s^2
Kinetic Energy = 40 J
Therefore, the kinetic energy of the bowling ball is 40 J.
So the correct answer is option a. 40 J.
To find the kinetic energy of an object, you can use the formula:
Kinetic Energy (KE) = 0.5 * mass * velocity^2
In this case, the mass of the bowling ball is given as 5.0 kg and the velocity is given as 4.0 m/s.
Plugging these values into the formula, we get:
KE = 0.5 * 5.0 kg * (4.0 m/s)^2
= 0.5 * 5.0 kg * 16.0 m^2/s^2
= 40 J
So the kinetic energy of the bowling ball is 40 J.
Therefore, the correct answer is option a. 40 J.
