Please atleast answer this question. 

A 76kg person takes an elevator downwards in a building. While in
the elevator, they wonder about the forces that act on them
during the elevator ride. Write all force vectors with a magnitude
and direction.
a. When they step in the elevator, it is not moving. Draw the free-
body diagram of the forces acting on the person. Calculate the
following forces acting on the person: net force, gravitational
force, normal force.
b. The elevator starts to accelerate downward with a magnitude of
1.1 m/s2. Draw the free-body diagram of the forces acting
the
person. Calculate the following orces acting on the person: net
force, gravitational force, normal force.
c. After the elevator accelerates, it moves downward at a constant
speed of 7 m/s. Draw the free-body diagram of the forces acting
on the person. Calculate the following forces acting on the person:
net force, gravitational force, normal force
