A 5.6kg bowling ball is rolled down a lane at 3.0m/s. What is the bowling balls Kinetic Energy.
K.E. = 1/2 m v^2 = 1/2 * 5.6 * 3.0^2 ... Joules
Well, well, well, we have a rolling bowling ball on our hands! To calculate the kinetic energy (KE) of this mighty ball, we can use the formula KE = 0.5 × mass × velocity squared. So, plugging in the numbers, we get KE = 0.5 × 5.6 kg × (3.0 m/s)². Crunching the numbers further, we find that the bowling ball has a kinetic energy of approximately 25.2 Joules. Time to knock down those pins, or perhaps invent a new sport of bowling with clowns!
To calculate the kinetic energy of the bowling ball, you can use the formula:
Kinetic Energy = 0.5 * mass * (velocity)^2
Given that the mass of the bowling ball is 5.6 kg and its velocity is 3.0 m/s, you can substitute these values into the formula:
Kinetic Energy = 0.5 * 5.6 kg * (3.0 m/s)^2
Calculating the values inside the parentheses:
Kinetic Energy = 0.5 * 5.6 kg * 9 m^2/s^2
Now, simplify the expression:
Kinetic Energy = 25.2 kg*m^2/s^2
The SI unit for energy is joules (J), therefore, the bowling ball's kinetic energy is 25.2 J.
To calculate the kinetic energy of an object, you can use the formula:
Kinetic Energy = (1/2) * mass * velocity^2
Given:
Mass (m) = 5.6 kg
Velocity (v) = 3.0 m/s
Substituting the given values into the formula, we get:
Kinetic Energy = (1/2) * 5.6 kg * (3.0 m/s)^2
Now, let's calculate the answer step by step:
Step 1: Square the velocity: (3.0 m/s)^2 = 9.0 m^2/s^2
Step 2: Multiply the squared velocity by the mass of the bowling ball: 5.6 kg * 9.0 m^2/s^2 = 50.4 kg⋅m^2/s^2
Step 3: Multiply the result by 1/2: (1/2) * 50.4 kg⋅m^2/s^2 = 25.2 kg⋅m^2/s^2
Therefore, the kinetic energy of the bowling ball is 25.2 kilogram meters squared per second squared (kg⋅m^2/s^2).
