Question

Pedro is driving a motorcycle along Espana boulevard. His position (in meters) at any given time is given by x(t) = 1.124t^{2} + 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/s^{2}.

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/s^{2}? m/s^{4}
