Rearrange the equation for time
(a * Vf) + Vi = t
a + Vi - Vf = t
t = (Vf - Vi) / a
t = Vf/a + Vi
8
What is the velocity of the blue car (80 mph) in the Cop's (60 MPH) reference frame.
120 MPH
20 MPH
140 MPH
50 MPH
9
Rearrange the equation for Vf
Vf = a*t + Vi
Vf = a*t / Vi
Vf = a*t - Vi
Vf = a / t + Vi
