Solution 1

Sure, let's calculate the potential energy (P.E) of the clock using the formula P.E = mgh.

Step 1: Identify the mass (m), gravity (g), and height (h). In this case, m=20 kg, g=9.8 m/s², and h=45 m.

Step 2: Substitute these values into the formula. So, P.E = 20 kg * 9.8 m/s² * 45 m.

Step 3: Calculate the result. The potential energy of the clock is 8820 Joules.

Solution 2

Sure, let's calculate the potential energy step by step:

  1. Identify the given values:

    • The mass (m) of the clock is 20 kg.
    • The height (h) of the tower is 45 m.
    • The acceleration due to gravity (g) is 9.8 m/s².

  2. Use the formula for potential energy (P.E), which is P.E = mgh.

  3. Substitute the given values into the formula:

    P.E = 20 kg * 9.8 m/s² * 45 m

  4. Multiply these values together to find the potential energy:

    P.E = 8820 Joules

So, the potential energy of the clock at the top of the tower is 8820 Joules.
