Problem 2:
An athlete, starting from rest, pulls handle A to the left with a constant force of P = 150 [N].
Knowing that after the handle A has been pulled 0.5 [m], its velocity is 5 [m/s] to the left,
determine:
a) A position constraint equation using the given coordinate system.
b) An acceleration constraint equation.
c) The acceleration of A using kinematics equations.
d) The acceleration of B using your constraint equation.
e) How much weight (magnitude) the athlete is lifting in pounds using Newton's 2nd Law.
You must draw a FBD and KD of the circled assembly, assuming the pulleys are
massless. Note: 1 [lbf] = 4.448 [N].
