Question
There is a clock at the top of a tower that is 45m high. The clock weighs 20 kg. Calculate its potential energy. Remember g=9.8 m/s
P.E = mgh
Solution
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.
