2. A cinder block is sitting on a platform 20 m high. It weighs 16kg. The block has _ joules of potential energy.

3136 Joules

Explanation:

Applying,

P.E = mgh Equation 1

Where P.E = potential energy, m = mass of the cinder block, h = height of the platform, g = acceleration due to gravity.

From the question,

Given: m = 16 kg, h = 20 m

Constant: g = 9.8 m/s²

Substitute these values into equation 1

P.E = 16(20)(9.8)

P.E = 3136 Joules

Hence the potential energy of the cinder block is 3136 Joules
