if the mass of a kettlebell is 2kg and julie swings it with a velocity of 5 m above the ground. what is the potential energy of the acorn. (PE=mgh g=9.81m/s^2)
Assuming you meant "potential energy of the kettlebell":
PE = mgh
where m = 2kg, g = 9.81m/s^2, and h = 5m
PE = 2kg x 9.81m/s^2 x 5m
PE = 98.1J
Therefore, the potential energy of the kettlebell is 98.1 Joules.
To determine the potential energy of the kettlebell, we'll need to follow these steps:
Step 1: Identify the given values.
Mass of the kettlebell (m) = 2 kg
Height above the ground (h) = 5 m
Acceleration due to gravity (g) = 9.81 m/s^2
Step 2: Apply the formula for potential energy.
Potential Energy (PE) = mass (m) × acceleration due to gravity (g) × height (h)
Step 3: Substitute the given values into the formula and calculate.
PE = 2 kg × 9.81 m/s^2 × 5 m
To calculate the potential energy, multiply the values:
PE = 98.1 kg m^2/s^2
Step 4: Determine the final result.
The potential energy of the kettlebell, when swung by Julie with a velocity of 5 m above the ground, is 98.1 kg m^2/s^2.
