Question
An elevator is initially moving upward at a speed of 13 m/s. The elevator experiences a constant downward acceleration of magnitude 3.5 m/s2 for 2.5 s.  You will be asked to find the elevator's final velocity.  What are the givens?
Group of answer choices
a = -3.5 m/s2, v= 13 m/s, t = 2.5 s
a = 3.5 m/s2, v0=13 m/s, t = 2.5 s
a = 3.5 m/s2, v0=13 m/s, vf = 0 m/s
a = -3.5 m/s2, vf=0 m/s, t = 2.5 s
