Because gravity...
If you dropped a brick and a spoon, they fall down at the same pace. Weight does not make items drop faster.

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:

Velocity of plane is given as
towards north
towards south east
we can write the two velocity in vector form


now the net velocity will be given as



so the resultant velocity will be given as


and the angle of velocity will be
