Question

Pedro is driving a motorcycle along Espana boulevard. His position  (in meters) at any given time  is given by x(t) = 1.124t2 + 6.022 . 

Pedro's initial position is   m.

His position at ten seconds is   m.

His speed at ten seconds is   m/s.

His acceleration at ten seconds is   m/s2.

 

Marites is also driving her motorcycle along Espana. Her position function is of the form . What is the coefficient  if her acceleration at ten seconds is 2.04 m/s2?   m/s4
