Please help me solve this I am confused

5 pts D Question 20 Suppose that an object's acceleration is given by a(t) = 8t + 9 meter per second squared. The object's initial velocity is v(0) = 5 meters per second and the initial position is s(0) = 9 meters. Find the position function s(t). O s ( t ) = + + 5t O s (1) = 412 + 9+ + 9 s ( 1 ) = 4 3 9 + 1 2 + 51 + 9 2 O s (1) = + -12 + 91 +5 NIV
