Question
1. List the kinematic equations you would choose to use in each of the following situations (i.e. the
most reasonable equations).
a. Translation: a = 4 ft/s?
b. Rotation: a = 10 rad/s
c. Translation: a= 2 cos e ft/s?, where 0 = 2t2 – 3 rad
d. Rotation: a = 2r rad/s?
For example, if asked for equations for a = 2t mph, I would note that acceleration is not
constant, and I would need the general translation kinematic equations:
dv
dr
v = -
dt
adr = vdv
a =-
dt
