PE is mgh in this context.
The combined mass of Danny+skateboard is 72.5 kg
Explanation:
We can solve the problem by using Newton's second law of motion:

where:
F is the net force applied on Danny and the skateboard
m is the mass of Danny+skateboard
a is the acceleration
Here we have the following data:
F = 29 N is the force applied
is the acceleration of Danny and the skateboard
Solving for m, we find their combined mass:
