Using the data provided in the graph and the table, interpolate to find the potential energy (U) at a height (H) of 2.5 meters and extrapolate to find the potential energy at a height of 4.5 meters.

Science questions require you to calculate values without ... Calculation questions require you to find a specific value based on the figures provided ... would happen past the edges of the graph or between values on a table ... at 75 m, this gap in data is what makes this an interpolation question!
