Answer:
The first derivative of 
(r(t)=5*t^{-2}) with respect to t is 
(r'(t) = -10*t^{-3}).
Step-by-step explanation:
Let be 
, which can be rewritten as . The rule of differentiation for a potential function multiplied by a constant is:
, 
Then,
(r'(t) = -10*t^{-3})
The first derivative of (r(t)=5*t^{-2}) with respect to t is (r'(t) = -10*t^{-3}).
